Pull ceph updates from Ilya Dryomov:
 "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"

rbd: support for object-map and fast-diff

2019-07-08T12:01:45+00:00

Speed up reads, discards and zeroouts through RBD_OBJ_FLAG_MAY_EXIST
and RBD_OBJ_FLAG_NOOP_FOR_NONEXISTENT based on object map.

Invalid object maps are not trusted, but still updated.  Note that we
never iterate, resize or invalidate object maps.  If object-map feature
is enabled but object map fails to load, we just fail the requester
(either "rbd map" or I/O, by way of post-acquire action).

libceph: export osd_req_op_data() macro

2019-07-08T12:01:45+00:00

We already have one exported wrapper around it for extent.osd_data and
rbd_object_map_update_finish() needs another one for cls.request_data.

libceph: change ceph_osdc_call() to take page vector for response

2019-07-08T12:01:45+00:00

This will be used for loading object map.  rbd_obj_read_sync() isn't
suitable because object map must be accessed through class methods.

This time for rbd object map.  Object maps are limited in size to
256000000 objects, two bits per object.

libceph: rename r_unsafe_item to r_private_item

2019-07-08T12:01:44+00:00

This list item remained from when we had safe and unsafe replies
(commit vs ack).  It has since become a private list item for use by
clients.

ceph: more precise CEPH_CLIENT_CAPS_PENDING_CAPSNAP

2019-07-08T12:01:44+00:00

Client uses this flag to tell mds if there is more cap snap need to
flush. It's mainly for the case that client needs to re-send cap/snap
flushes after mds failover, but CEPH_CAP_ANY_FILE_WR on corresponding
inodes are all released before mds failover.

...ditto for the decode function. We only use these functions to fix
up banner addresses now, so let's name them more appropriately.
