Merge tag 'ceph-for-4.11-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov:
"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"
