Subject: [GIT PULL] Ceph updates for 5.1-rc1
Hi Linus,
The following changes since commit 1c163f4c7b3f621efff9b28a47abb36f7378d783:
Linux 5.0 (2019-03-03 15:21:29 -0800)
are available in the Git repository at:
https://github.com/ceph/ceph-client.git tags/ceph-for-5.1-rc1

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)
----------------------------------------------------------------
