Partially revert e69edc79, which introduced automatic zreladdr support. The change in the way the manual definition is defined seems to be error and conflict prone. Go back to the original way we were handling this for the time being, while keeping the automatic zreladdr facility.

lg_lock_global() currently only acquires spinlocks for online CPUs, but it's meant to lock all possible CPUs. Lglock-protected resources may be associated with removed CPUs - and, indeed, that could happen with the per-superblock open files lists. At Nick's suggestion, change for_each_online_cpu() to for_each_possible_cpu() to protect accesses to those resources.

During a stress testing in a large cluster, multiple close event are detected and BUG() is hit in the iWARP core. The cause is that the active node gave up while waiting for an MPA response from the peer and tried to close the connection by sending RST. The passive node driver receives the RST but is waiting for MPA response from the user. When the MPA accept is received, the driver offloads the connection and sends a CLOSE event. The driver gets an AE indicating RESET received and also sends a CLOSE event, hitting a BUG(). Fix this by correcting RESET handling and sending CLOSE events.

Dave Hylands reports: | We've observed a problem with dma_alloc_writecombine when the system | is under heavy load (heavy bus traffic). We've managed to reduce the | problem to the following snippet, which is run from a kthread in a | continuous loop: | | void *virtAddr; | dma_addr_t physAddr; | unsigned int numBytes = 256; | | for (;;) { | virtAddr = dma_alloc_writecombine(NULL, | numBytes, &physAddr, GFP_KERNEL); | if (virtAddr == NULL) { | printk(KERN_ERR "Running out of memory\n"); | break; | } | | /* access DMA memory allocated */ | tmp = virtAddr; | *tmp = 0x77; | | /* free DMA memory */ | dma_free_writecombine(NULL, | numBytes, virtAddr, physAddr); | | ...sleep here... | } | | By itself, the code will run forever with no issues. However, as we | increase our bus traffic (typically using DMA) then the *tmp = 0x77 | line will eventually cause a page fault. If we add a small delay (a | few microseconds) before the *tmp = 0x77, then we don't see a page | fault, even under heavy load. A dsb() is required after modifying the PTE entries to ensure that they will always be visible. Add this dsb().

Commit 7cfe2494 ("ARM: AMBA: Add pclk support to AMBA bus infrastructure") changed AMBA bus to handle the PCLK automatically. However, in EP93xx clock initialization is arch_initcall which is done later than AMBA device identification. This causes amba_get_enable_pclk() to fail resulting device where UARTs are not functional. So change ep93xx_clock_init() to be postcore_initcall.

ocfs2_create_inode_in_orphan() is used by reflink to create the newly reflinked inode simultaneously in the orphan dir. This allows us to easily handle partially-reflinked files during recovery cleanup. We have a problem though - the orphan dir stringifies inode # to determine a unique name under which the orphan entry dirent can be created. Since ocfs2_create_inode_in_orphan() needs the space allocated in the orphan dir before it can allocate the inode, we currently call into the orphan code: /* * We give the orphan dir the root blkno to fake an orphan name, * and allocate enough space for our insertion. */ status = ocfs2_prepare_orphan_dir(osb, &orphan_dir, osb->root_blkno, orphan_name, &orphan_insert); Using osb->root_blkno might work fine on unindexed directories, but the orphan dir can have an index. When it has that index, the above code fails to allocate the proper index entry. Later, when we try to remove the file from the orphan dir (using the actual inode #), the reflink operation will fail. To fix this, I created a function ocfs2_alloc_orphaned_file() which uses the newly split out orphan and inode alloc code to figure out what the inode block number will be (once allocated) and then prepare the orphan dir from that data.

We do this because ocfs2_create_inode_in_orphan() wants to order locking of the orphan dir with respect to locking of the inode allocator *before* making any changes to the directory. Signed-off-by: NMark Fasheh <mfasheh@suse.com> Signed-off-by: NTao Ma <tao.ma@oracle.com>

This allows code which needs to know the eventual block number of an inode but can't allocate it yet due to transaction or lock ordering. For example, ocfs2_create_inode_in_orphan() currently gives a junk blkno for preparation of the orphan dir because it can't yet know where the actual inode is placed - that code is actually in ocfs2_mknod_locked. This is a problem when the orphan dirs are indexed as the junk inode number will create an index entry which goes unused (and fails the later removal from the orphan dir). Now with these interfaces, ocfs2_create_inode_in_orphan() can run the block group search (and get back the inode block number) *before* any actual allocation occurs.

For local mounts, ocfs2_read_locked_inode() calls ocfs2_read_blocks_sync() to read the inode off the disk. The latter first checks to see if that block is cached in the journal, and, if so, returns that block. That is ok. But ocfs2_read_locked_inode() goes wrong when it tries to validate the checksum of such blocks. Blocks that are cached in the journal may not have had their checksum computed as yet. We should not validate the checksums of such blocks.

This patch updates the counters, whether or not IMA has been initialized, to resolve 'imbalance' messages. This patch fixes the bug as reported in bugzilla: 15673.
