According to ceph documentation [1], "getfattr -d /some/dir" no longer
displays the list of all extended attributes. Both CephFS kernel and
FUSE clients hide this information.
To retrieve the information you have to specify the particular attribute
name e.g. "getfattr -n ceph.dir.rbytes /some/dir".

Sage's git tree has not been pushed to in years, and it was removed in
commit 3a5ccecd9a ("MAINTAINERS: remove myself as ceph co-maintainer"),
so it is better to remove it in the documentation too.

- support for asynchronous create and unlink (Jeff Layton). Creates
and unlinks are satisfied locally, without waiting for a reply from
the MDS, provided the client has been granted appropriate caps (new
in v15.y.z ("Octopus") release). This can be a big help for metadata
heavy workloads such as tar and rsync. Opt-in with the new nowsync
mount option.
- multiple blk-mq queues for rbd (Hannes Reinecke and myself). When
the driver was converted to blk-mq, we settled on a single blk-mq
queue because of a global lock in libceph and some other technical
debt. These have since been addressed, so allocate a queue per CPU
to enhance parallelism.
- don't hold onto caps that aren't actually needed (Zheng Yan). This
has been our long-standing behavior, but it causes issues with some
active/standby applications (synchronous I/O, stalls if the standby
goes down, etc).
- .snap directory timestamps consistent with ceph-fuse (Luis Henriques)
