Fix exit race by splitting the nsproxy putting into two pieces. First piece reduces the nsproxy refcount. If we dropped the last reference, then it puts the mnt_ns, and returns the nsproxy as a hint to the caller. Else it returns NULL. The second piece of exiting task namespaces sets tsk->nsproxy to NULL, and drops the references to other namespaces and frees the nsproxy only if an nsproxy was passed in. A little awkward and should probably be reworked, but hopefully it fixes the NFS oops. Signed-off-by: NSerge E.

This makes balance_dirty_page() always base its calculations on the amount of non-highmem memory in the machine, rather than try to base it on total memory and then falling back on non-highmem memory if the mapping it was writing wasn't highmem capable. This not only fixes a situation where two different writers can have wildly different notions about what is a "balanced" dirty state, but it also means that people with highmem machines don't run into an OOM situation when regular memory fills up with dirty pages. We used to try to handle the latter case by scaling down the dirty_ratio if the machine had a lot of highmem pages in page_writeback_init(), but it wasn't aggressive enough for some situations, and since basing the dirty ratio on highmem memory was broken in the first place, let's just stop doing so. (A variation of this theme fixed Justin Piszcz's OOM problem when copying an 18GB file on a RAID setup).

Mirror the logic in the sun4u handler, we have to update both registers even when we branch out to window fault fixup handling. The way it works is that if we are in etrap processing a fault already, g4/g5 holds the original fault information. If we take a window spill fault while doing etrap, then we put the window spill fault info into g4/g5 and this is what the top-level fault handler ends up processing first. Then we retry the originally faulting instruction, and process the original fault at that time. This is all necessary because of how constrained the trap registers are in these code paths. These cases trigger very rarely, so even if there is some performance implication it's doesn't happen very often. In fact the rarity is why it took so long to trigger and find this particular bug.

由 David Woodhouse 提交于
On the Maple board, the AMD8111 IDE is in legacy mode... except that it appears on IRQ 20 instead of IRQ 15. For drivers/ide this was handled by the architecture's "pci_get_legacy_ide_irq()" function, but in libata we just hard-code the numbers 14 and 15. This patch provides asm-powerpc/libata-portmap.h which maps the IRQ as appropriate, having added a pci_dev argument to the ATA_{PRIM,SECOND}ARY_IRQ macros. There's probably a better way to do this -- especially if we observe that the _only_ case in which this seemingly-generic "pci_get_legacy_ide_irq()" function returns anything other than 14 and 15 for primary and secondary respectively is the case of the AMD8111 on the Maple board -- couldn't we handle that with a special case in the pata_amd driver, or perhaps with a PCI quirk for Maple to switch it into native mode during early boot and assign resources properly?

Before hardreset, ahci initialized stat part of received FIS area to 0xff to wait for the first D2H Reg FIS which would change the value to device ready state. This used to work but now libata considers status value of 0xff as device not present making this wait prone to failure. This patch makes ahci use 0x80 for the wait stat value instead of 0xff to fix the above problem.

If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held, it is possible for a deadlock to eventuate. This happens if the array was marked 'clean', and the memalloc triggers a write-out to the md device. For the writeout to succeed, the array must be marked 'dirty', and that requires getting the mddev_lock. So, before attempting a GFP_KERNEL allocation while holding the lock, make sure the array is marked 'dirty' (unless it is currently read-only).

nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now. Less internal (to nfsd) checking offset by more external checking, which is more important. Thanks to Gabriel Paubert <paubert@iram.es> for discovering this and providing an initial patch.

Allow noflush suspend/resume of device-mapper device only for the case where the device size is unchanged. Otherwise, dm-multipath devices can stall when resumed if noflush was used when suspending them, all paths have failed and queue_if_no_path is set. Explanation: 1. Something is doing fsync() on the block dev, holding inode->i_sem 2. The fsync write is blocked by all-paths-down and queue_if_no_path 3. Someone requests to suspend the dm device with noflush. Pending writes are left in queue. 4. In the middle of dm_resume(), __bind() tries to get inode->i_sem to do __set_size() and waits forever. 'noflush suspend' is a new device-mapper feature introduced in early 2.6.20. So I hope the fix being included before 2.6.20 is released. Example of reproducer: 1. Create a multipath device by dmsetup 2. Fail all paths during mkfs 3. Do dmsetup suspend --noflush and load new map with healthy paths 4.
