Pull btrfs updates from David Sterba:
 "This time the majority of changes are cleanups, though there's still a
  number of changes of user interest.
  User visible changes:
   - better read time and write checks to catch errors early and before
     writing data to disk (to catch potential memory corruption on data
     that get checksummed)
   - qgroups + metadata relocation: last speed up patch int the series
     to address the slowness, there should be no overhead comparing
     balance with and without qgroups
   - FIEMAP ioctl does not start a transaction unnecessarily, this can
     result in a speed up and less blocking due to IO
   - LOGICAL_INO (v1, v2) does not start transaction unnecessarily, this
     can speed up the mentioned ioctl and scrub as well
   - fsync on files with many (but not too many) hardlinks is faster,
     finer decision if the links should be fsynced individually or
     completely
   - send tries harder to find ranges to clone
   - trim/discard will skip unallocated chunks that haven't been touched
     since the last mount
  Fixes:
   - send flushes delayed allocation before start, otherwise it could
     miss some changes in case of a very recent rw->ro switch of a
     subvolume
   - fix fallocate with qgroups that could lead to space accounting
     underflow, reported as a warning
   - trim/discard ioctl honours the requested range
   - starting send and dedupe on a subvolume at the same time will let
     only one of them succeed, this is to prevent changes that send
     could miss due to dedupe; both operations are restartable
  Core changes:
   - more tree-checker validations, errors reported by fuzzing tools:
      - device item
      - inode item
      - block group profiles
   - tracepoints for extent buffer locking
   - async cow preallocates memory to avoid errors happening too deep in
     the call chain
   - metadata reservations for delalloc reworked to better adapt in
     many-writers/low-space scenarios
   - improved space flushing logic for intense DIO vs buffered workloads
   - lots of cleanups
      - removed unused struct members
      - redundant argument removal
      - properties and xattrs
      - extent buffer locking
      - selftests
      - use common file type conversions
      - many-argument functions reduction"
