  libceph, rbd, ceph: WRITE | ONDISK -> WRITE (2017-02-24 19:04:57 +0100)

----------------------------------------------------------------
This time around we have:

- support for rbd data-pool feature, which enables rbd images on
  erasure-coded pools (myself).  CEPH_PG_MAX_SIZE has been bumped to
  allow erasure-coded profiles with k+m up to 32.

- a patch for ceph_d_revalidate() performance regression introduced in
  4.9, along with some cleanups in the area (Jeff Layton)

- a set of fixes for unsafe ->d_parent accesses in CephFS (Jeff Layton)

- buffered reads are now processed in rsize windows instead of rasize
  windows (Andreas Gerstmayr).  The new default for rsize mount option
  is 64M.

- ack vs commit distinction is gone, greatly simplifying ->fsync() and
  MOSDOpReply handling code (myself)

Also a few filesystem bug fixes from Zheng, a CRUSH sync up (CRUSH
computations are still serialized though) and several minor fixes and
cleanups all over.
