  Documentation: modern versions of ceph are not backed by btrfs (2019-03-05 18:55:18 +0100)

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

- rbd will now ignore discards that aren't aligned and big enough to
  actually free up some space (myself).  This is controlled by the new
  alloc_size map option and can be disabled if needed.

- support for rbd deep-flatten feature (myself).  Deep-flatten allows
  "rbd flatten" to fully disconnect the clone image and its snapshots
  from the parent and make the parent snapshot removable.

- a new round of cap handling improvements (Zheng Yan).  The kernel
  client should now be much more prompt about releasing its caps and
  it is possible to put a limit on the number of caps held.

- support for getting ceph.dir.pin extended attribute (Zheng Yan)

----------------------------------------------------------------
