Linus Torvalds fca0e39b2b Changes since last update:
- Fix a locking problem during xattr block conversion that could lead to
   the log checkpointing thread to try to write an incomplete buffer to
   disk, which leads to a corruption shutdown
 - Fix a null pointer dereference when removing delayed allocation extents
 - Remove post-eof speculative allocations when reflinking a block past
   current inode size so that we don't just leave them there and assert on
   inode reclaim
 - Relax an assert which didn't accurately reflect the way locking works
   and would trigger under heavy io load
 - Avoid infinite loop when cancelling copy on write extents after a
   writeback failure
 - Try to avoid copy on write transaction reservation overflows when
   remapping after a successful write
 - Fix various problems with the copy-on-write reservation automatic
   garbage collection not being cleaned up properly during a ro remount
 - Fix problems with rmap log items being processed in the wrong order,
   leading to corruption shutdowns
 - Fix problems with EFI recovery wherein the "remove any rmapping if
   present" mechanism wasn't actually doing anything, which would lead
   to corruption problems later when the extent is reallocated, leading
   to multiple rmaps for the same extent

Pull xfs fixes from Darrick Wong:
 "Here are some XFS fixes for 4.15-rc5. Apologies for the unusually
  large number of patches this late, but I wanted to make sure the
  corruption fixes were really ready to go.

  Changes since last update:

   - Fix a locking problem during xattr block conversion that could lead
     to the log checkpointing thread to try to write an incomplete
     buffer to disk, which leads to a corruption shutdown

   - Fix a null pointer dereference when removing delayed allocation
     extents

   - Remove post-eof speculative allocations when reflinking a block
     past current inode size so that we don't just leave them there and
     assert on inode reclaim

   - Relax an assert which didn't accurately reflect the way locking
     works and would trigger under heavy io load

   - Avoid infinite loop when cancelling copy on write extents after a
     writeback failure

   - Try to avoid copy on write transaction reservation overflows when
     remapping after a successful write

   - Fix various problems with the copy-on-write reservation automatic
     garbage collection not being cleaned up properly during a ro
     remount

   - Fix problems with rmap log items being processed in the wrong
     order, leading to corruption shutdowns

   - Fix problems with EFI recovery wherein the "remove any rmapping if
     present" mechanism wasn't actually doing anything, which would lead
     to corruption problems later when the extent is reallocated,
     leading to multiple rmaps for the same extent"
