Pull ARM SoC board specific changes from Arnd Bergmann: "These are 18 branches on 9 platforms with board specific changes, mostly for defconfig files, but nothing really exciting in here. Since the shmobile platform still uses board files for some of the newer machines, we get a few changes there as the result of drivers getting enabled for those boards. This causes some conflicts with contents getting added from multiple branches in sh-mobile specific files. Renesas is putting a lot of work into migrating to device-tree based setup, which will make all those files obsolete in the future and avoid both the conflicts and the need to have these files in the first place." * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (49 commits) arm: multi_v7_defconfig: Enable initrd/initramfs support arm: multi_v7_defconfig: Enable Zynq UART driver ARM: omap2plus_defconfig: enable USB_PHY and NOP_USB_XCEIV ARM: OMAP1: nokia770: enable Tahvo ARM: OMAP3EVM: Marking omap3_evm_display_init() with CONFIG_BROKEN arm: omap: board-overo: reset GPIO for SMSC911x ARM: shmobile: BOCK-W: change Ether device name ARM: ux500: board-mop500: remove unused pin modes ARM: shmobile: bockw: add MMCIF support ARM: shmobile: bockw: add SPI FLASH support ARM: shmobile: bockw: add I2C device support ARM: shmobile: BOCK-W: add Ether support ARM: tegra: defconfig updates ARM: shmobile: bockw defconfig: add MMCIF support ARM: shmobile: bockw defconfig: add M25P80 support ARM: shmobile: bockw defconfig: add RTC RX8581 support ARM: shmobile: marzen: keep local function as static ARM: shmobile: bockw: add SDHI0 support ARM: shmobile: marzen: Use INTC External IRQ pin driver for SMSC ARM: shmobile: lager: support GPIO switches ...

Pull ARM SoC specific changes from Arnd Bergmann: "These changes are all to SoC-specific code, a total of 33 branches on 17 platforms were pulled into this. Like last time, Renesas sh-mobile is now the platform with the most changes, followed by OMAP and EXYNOS. Two new platforms, TI Keystone and Rockchips RK3xxx are added in this branch, both containing almost no platform specific code at all, since they are using generic subsystem interfaces for clocks, pinctrl, interrupts etc. The device drivers are getting merged through the respective subsystem maintainer trees. One more SoC (u300) is now multiplatform capable and several others (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving towards that goal with this series but need more work. Also noteworthy is the work on PCI here, which is traditionally part of the SoC specific code. With the changes done by Thomas Petazzoni, we can now more easily have PCI host controller drivers as loadable modules and keep them separate from the platform code in drivers/pci/host. This has already led to the discovery that three platforms (exynos, spear and imx) are actually using an identical PCIe host controller and will be able to share a driver once support for spear and imx is added." * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (480 commits) ARM: integrator: let pciv3 use mem/premem from device tree ARM: integrator: set local side PCI addresses right ARM: dts: Add pcie controller node for exynos5440-ssdk5440 ARM: dts: Add pcie controller node for Samsung EXYNOS5440 SoC ARM: EXYNOS: Enable PCIe support for Exynos5440 pci: Add PCIe driver for Samsung Exynos ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data ARM: keystone: Move CPU bringup code to dedicated asm file ARM: multiplatform: always pick one CPU type ARM: imx: select syscon for IMX6SL ARM: keystone: select ARM_ERRATA_798181 only for SMP ARM: imx: Synertronixx scb9328 needs to select SOC_IMX1 ARM: OMAP2+: AM43x: resolve SMP related build error dmaengine: edma: enable build for AM33XX ARM: edma: Add EDMA crossbar event mux support ARM: edma: Add DT and runtime PM support to the private EDMA API dmaengine: edma: Add TI EDMA device tree binding arm: add basic support for Rockchip RK3066a boards arm: add debug uarts for rockchip rk29xx and rk3xxx series arm: Add basic clocks for Rockchip rk3066a SoCs ...

In the bug fixes category, of note is a fix for on-line resizing file systems where the block size is smaller than the page size (i.e., file systems 1k blocks on x86, or more interestingly file systems with 4k blocks on Power or ia64 systems.) In the cleanup category, the ext4's punch hole implementation was significantly improved by Lukas Czerner, and now supports bigalloc file systems. In addition, Jan Kara significantly cleaned up the write submission code path. We also improved error checking and added a few sanity checks. In the optimizations category, two major optimizations deserve mention. The first is that ext4_writepages() is now used for nodelalloc and ext3 compatibility mode. This allows writes to be submitted much more efficiently as a single bio request, instead of being sent as individual 4k writes into the block layer (which then relied on the elevator code to coalesce the requests in the block queue). Secondly, the extent cache shrink mechanism, which was introduce in 3.9, no longer has a scalability bottleneck caused by the i_es_lru spinlock.

由 Dave Chinner 提交于
When sync does it's WB_SYNC_ALL writeback, it issues data Io and then immediately waits for IO completion. This is done in the context of the flusher thread, and hence completely ties up the flusher thread for the backing device until all the dirty inodes have been synced. On filesystems that are dirtying inodes constantly and quickly, this means the flusher thread can be tied up for minutes per sync call and hence badly affect system level write IO performance as the page cache cannot be cleaned quickly. We already have a wait loop for IO completion for sync(2), so cut this out of the flusher thread and delegate it to wait_sb_inodes(). Hence we can do rapid IO submission, and then wait for it all to complete. Effect of sync on fsmark before the patch: FSUse% Count Size Files/sec App Overhead ..... 0 640000 4096 35154.6 1026984 0 720000 4096 36740.3 1023844 0 800000 4096 36184.6 916599 0 880000 4096 1282.7 1054367 0 960000 4096 3951.3 918773 0 1040000 4096 40646.2 996448 0 1120000 4096 43610.1 895647 0 1200000 4096 40333.1 921048 And a single sync pass took: real 0m52.407s user 0m0.000s sys 0m0.090s After the patch, there is no impact on fsmark results, and each individual sync(2) operation run concurrently with the same fsmark workload takes roughly 7s: real 0m6.930s user 0m0.000s sys 0m0.039s IOWs, sync is 7-8x faster on a busy filesystem and does not have an adverse impact on ongoing async data write operations.

If user requests many data writes and fsync together, the last updated i_size should be stored to the inode block consistently. But, previous write_end just marks the inode as dirty and doesn't update its metadata into its inode block. After that, fsync just writes the inode block with newly updated data index excluding inode metadata updates. So, this patch introduces write_end in which updates inode block too when the i_size is changed. Signed-off-by: NJaegeuk Kim <jaegeuk.kim@samsung.com>

This patch removes check_prefree_segments initially designed to enhance the performance by narrowing the range of LBA usage across the whole block device. When allocating a new segment, previous f2fs tries to find proper prefree segments, and then, if finds a segment, it reuses the segment for further data or node block allocation. However, I found that this was totally wrong approach since the prefree segments have several data or node blocks that will be used by the roll-forward mechanism operated after sudden-power-off. Let's assume the following scenario. /* write 8MB with fsync */ for (i = 0; i < 2048; i++) { offset = i * 4096; write(fd, offset, 4KB); fsync(fd); } In this case, naive segment allocation sequence will be like: data segment: x, x+1, x+2, x+3 node segment: y, y+1, y+2, y+3. But, if we can reuse prefree segments, the sequence can be like: data segment: x, x+1, y, y+1 node segment: y, y+1, y+2, y+3. Because, y, y+1, and y+2 became prefree segments one by one, and those are reused by data allocation. After conducting this workload, we should consider how to recover the latest inode with its data. If we reuse the prefree segments such as y or y+1, we lost the old node blocks so that f2fs even cannot start roll-forward recovery. Therefore, I suggest that we should remove reusing prefree segments. Signed-off-by: NJaegeuk Kim <jaegeuk.kim@samsung.com>

Optimize the while loop condition Since this condition will always be true and while loop will be terminated by the following condition in code: if (segno >= TOTAL_SEGS(sbi)) break; Hence we can replace the while loop condition with while(1) instead of always checking for segno to be less than Total segs. Also we do not need to use TOTAL_SEGS() everytime. We can store this value in a local variable since this value is constant.

Both hole punch and truncate use ext4_ext_rm_leaf() for removing blocks. Currently we choose the last extent as the starting point for removing blocks: ex = EXT_LAST_EXTENT(eh); This is OK for truncate but for hole punch we can optimize the extent selection as the path is already initialized. We could use this information to select proper starting extent. The code change in this patch will not affect truncate as for truncate path[depth].p_ext will always be NULL.

If jbd2_journal_restart() fails the handle will have been disconnected from the current transaction. In this situation, the handle must not be used for for any jbd2 function other than jbd2_journal_stop(). Enforce this with by treating a handle which has a NULL transaction pointer as an aborted handle, and issue a kernel warning if jbd2_journal_extent(), jbd2_journal_get_write_access(), jbd2_journal_dirty_metadata(), etc. is called with an invalid handle. This commit also fixes a bug where jbd2_journal_stop() would trip over a kernel jbd2 assertion check when trying to free an invalid handle. Also move the responsibility of setting current->journal_info to start_this_handle(), simplifying the three users of this function.

The function mpage_released_unused_page() must only be called once; otherwise the kernel will BUG() when the second call to mpage_released_unused_page() tries to unlock the pages which had been unlocked by the first call. Also restructure the error handling so that we only give up on writing the dirty pages in the case of ENOSPC where retrying the allocation won't help. Otherwise, a transient failure, such as a kmalloc() failure in calling ext4_map_blocks() might cause us to give up on those pages, leading to a scary message in /var/log/messages plus data loss.

Once we decrement transaction->t_updates, if this is the last handle holding the transaction from closing, and once we release the t_handle_lock spinlock, it's possible for the transaction to commit and be released. In practice with normal kernels, this probably won't happen, since the commit happens in a separate kernel thread and it's unlikely this could all happen within the space of a few CPU cycles. On the other hand, with a real-time kernel, this could potentially happen, so save the tid found in transaction->t_tid before we release t_handle_lock. It would require an insane configuration, such as one where the jbd2 thread was set to a very high real-time priority, perhaps because a high priority real-time thread is trying to read or write to a file system. But some people who use real-time kernels have been known to do insane things, including controlling laser-wielding industrial robots. :-) Signed-off-by: N"Theodore Ts'o" <tytso@mit.edu> Cc: stable@vger.kernel.org

Now we maintain an proper in-order LRU list in ext4 to reclaim entries from extent status tree when we are under heavy memory pressure. For keeping this order, a spin lock is used to protect this list. But this lock burns a lot of CPU time. We can use the following steps to trigger it. % cd /dev/shm % dd if=/dev/zero of=ext4-img bs=1M count=2k % mkfs.ext4 ext4-img % mount -t ext4 -o loop ext4-img /mnt % cd /mnt % for ((i=0;i<160;i++)); do truncate -s 64g $i; done % for ((i=0;i<160;i++)); do cp $i /dev/null &; done % perf record -a -g % perf report This commit tries to fix this problem. Now a new member called i_touch_when is added into ext4_inode_info to record the last access time for an inode. Meanwhile we never need to keep a proper in-order LRU list. So this can avoid to burns some CPU time. When we try to reclaim some entries from extent status tree, we use list_sort() to get a proper in-order list. Then we traverse this list to discard some entries. In ext4_sb_info, we use s_es_last_sorted to record the last time of sorting this list. When we traverse the list, we skip the inode that is newer than this time, and move this inode to the tail of LRU list. When the head of the list is newer than s_es_last_sorted, we will sort the LRU list again. In this commit, we break the loop if s_extent_cache_cnt == 0 because that means that all extents in extent status tree have been reclaimed. Meanwhile in this commit, ext4_es_{un}register_shrinker()'s prototype is changed to save a local variable in these functions.

If memory allocation in ext4_mb_new_group_pa() is failed, it returns error code, ext4_mb_new_preallocation() propages it, but ext4_mb_new_blocks() ignores it. An observed result was: - allocation fail means ext4_mb_new_group_pa() does not update ext4_allocation_context; - ext4_mb_new_blocks() sets ext4_allocation_request->len (ar->len = ac->ac_b_ex.fe_len;) to number of blocks preallocated (512) instead of number of blocks requested (1); - that activates update cycle in ext4_splice_branch(): for (i = 1; i < blks; i++) <-- blks is 512 instead of 1 here *(where->p + i) = cpu_to_le32(current_block++); - it iterates 511 times and corrupts a chunk of memory including inode structure; - page fault happens at EXT4_SB(inode->i_sb) in ext4_mark_inode_dirty(); - system hangs with 'scheduling while atomic' BUG.
