Hi Linus,

The following changes since commit 0ecfebd2b52404ae0c54a878c872bb93363ada36:

Linux 5.2 (2019-07-07 15:41:56 -0700)

ceph: fix end offset in truncate_inode_pages_range call (2019-07-08 14:01:45 +0200)

There is a trivial conflict caused by commit 9ffbe8ac05db
("locking/lockdep: Rename lockdep_assert_held_exclusive() ->
lockdep_assert_held_write()"). I included the resolution in
for-linus-merged.

----------------------------------------------------------------
Lots of exciting things this time!

- support for rbd object-map and fast-diff features (myself). This
will speed up reads, discards and things like snap diffs on sparse
images.

- ceph.snap.btime vxattr to expose snapshot creation time (David
Disseldorp). This will be used to integrate with "Restore Previous
Versions" feature added in Windows 7 for folks who reexport ceph
through SMB.

- security xattrs for ceph (Zheng Yan). Only selinux is supported
for now due to the limitations of ->dentry_init_security().

- support for MSG_ADDR2, FS_BTIME and FS_CHANGE_ATTR features (Jeff
Layton). This is actually a single feature bit which was missing
because of the filesystem pieces. With this in, the kernel client
will finally be reported as "luminous" by "ceph features" -- it is
still being reported as "jewel" even though all required Luminous
features were implemented in 4.13.

- stop NULL-terminating ceph vxattrs (Jeff Layton). The convention
with xattrs is to not terminate and this was causing inconsistencies
with ceph-fuse.

- change filesystem time granularity from 1 us to 1 ns, again fixing
an inconsistency with ceph-fuse (Luis Henriques).

On top of this there are some additional dentry name handling and cap
flushing fixes from Zheng. Finally, Jeff is formally taking over for
Zheng as the filesystem maintainer.
