Hi Linus,

The following changes since commit 4d856f72c10ecb060868ed10ff1b1453943fc6c8:

  Linux 5.3 (2019-09-15 14:19:32 -0700)

  ceph: call ceph_mdsc_destroy from destroy_fs_client (2019-09-16 12:06:25 +0200)

----------------------------------------------------------------
The highlights are:

- automatic recovery of a blacklisted filesystem session (Zheng Yan).
  This is disabled by default and can be enabled by mounting with the
  new "recover_session=clean" option.

- serialize buffered reads and O_DIRECT writes (Jeff Layton).  Care is
  taken to avoid serializing O_DIRECT reads and writes with each other,
  this is based on the exclusion scheme from NFS.

- handle large osdmaps better in the face of fragmented memory (myself)

- don't limit what security.* xattrs can be get or set (Jeff Layton).
  We were overly restrictive here, unnecessarily preventing things like
  file capability sets stored in security.capability from working.

- allow copy_file_range() within the same inode and across different
  filesystems within the same cluster (Luis Henriques)
