Last night we had scsi problems and a hardware raid unit was offlined during heavy i/o. While this happened we got for about 3 minutes a huge number messages like these Apr 12 03:36:07 pfs1n14 kernel: [197510.696595] raid5:md7: read error not correctable (sector 2993096568 on sdj2). I guess the high error rate is responsible for not scheduling other events - during this time the system was not pingable and in the end also other devices run into scsi command timeouts causing problems on these unrelated devices as well.

It is possible to add a write-intent bitmap to an active array, or remove the bitmap that is there. When we do with the 'quiesce' the array, which causes make_request to block in "wait_barrier()". However we are sampling the value of "mddev->bitmap" before the wait_barrier call, and using it afterwards. This can result in using a bitmap structure that has been freed.

Fuse allocates a separate bdi for each filesystem, and registers them in sysfs with "MAJOR:MINOR" of sb->s_dev (st_dev). This works fine for anon devices normally used by fuse, but can conflict with an already registered BDI for "fuseblk" filesystems, where sb->s_dev represents a real block device. In particularl this happens if a non-partitioned device is being mounted. Fix by registering with a different name for "fuseblk" filesystems. Thanks to Ioan Ionita for the bug report.

If a low-level driver returns IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_CONSUMED, handle_outgoing_dr_smp() doesn't clean up properly. The fix is to kfree the local data and break, rather than falling through. This was observed with the ipath driver, but could happen with any driver.

When we have multiple buffers in a single page for a blocksize == pagesize filesystem we might overwrite the page contents if two callers hit it shortly after each other. To prevent that we need to keep the page locked until I/O is completed and the page marked uptodate. Thanks to Eric Sandeen for triaging this bug and finding a reproducible testcase and Dave Chinner for additional advice. This should fix kernel.org bz #10421.

Protect against this by returning if mpic is NULL in mpic_irq_set_priority, and removing mpic_irq_get_priority completely as it has no in tree callers.

Since commit "85xx: Add support for relocatable kernel (and booting at non-zero)" (37dd2bad), PHYSICAL_START is #defined as kernstart_addr if RELOCATABLE and FLATMEM is enabled. PHYSICAL_START is used in prom_init.c and so kernstart_addr needs to be added to the list of allowed symbols that prom_init.c can access.

A change was made to walk_memory_resource() in commit 4b119e21 that added a check of find_lmb(). Add the coresponding lmb_add() call to ps3_mm_add_memory() so that that check will succeed. This fixes the condition where the PS3 boots up with only the 128 MiB of boot memory, and doesn't see the other 128MiB that is available.

We only need to allocate space for the number of inodes in the cluster when writing back inodes, not every byte in the inode cluster.

writeback If we allow memory reclaim to wait on the pages under writeback in inode cluster writeback we could deadlock because we are currently holding the ILOCK on the initial writeback inode which is needed in data I/O completion to change the file size or do unwritten extent conversion before the pages are taken out of writeback state.

xfs_fsync() fails to wait for data I/O completion before checking if the inode is dirty or clean to decide whether to log the inode or not. This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.
