Hi Linus,
The following changes since commit 3d77e6a8804abcc0504c904bd6e5cdf3a5cf8162:
Linux 5.7 (2020-05-31 16:49:15 -0700)

rbd: compression_hint option (2020-06-01 23:32:35 +0200)
----------------------------------------------------------------
The highlights are:
- OSD/MDS latency and caps cache metrics infrastructure for the
filesytem (Xiubo Li). Currently available through debugfs and
will be periodically sent to the MDS in the future.
- support for replica reads (balanced and localized reads) for
rbd and the filesystem (myself). The default remains to always
read from primary, users can opt-in with the new crush_location
and read_from_replica options. Note that reading from replica
is safe for general use only since Octopus.
- support for RADOS allocation hint flags (myself). Currently
used by rbd to propagate the compressible/incompressible hint
given with the new compression_hint map option and ready for
passing on more advanced hints, e.g. based on fadvise() from
the filesystem.
- support for efficient cross-quota-realm renames (Luis Henriques)
- assorted cap handling improvements and cleanups, particularly
untangling some of the locking (Jeff Layton)
----------------------------------------------------------------
Gustavo A. R. Silva (1):
libceph, rbd: replace zero-length array with flexible-array
Ilya Dryomov (7):
libceph: add non-asserting rbtree insertion helper
libceph: decode CRUSH device/bucket types and names
libceph: crush_location infrastructure
libceph: support for balanced and localized reads
libceph: read_from_replica option
libceph: support for alloc hint flags

Jeff Layton (11):
ceph: reorganize __send_cap for less spinlock abuse
ceph: split up __finish_cap_flush
ceph: add comments for handle_cap_flush_ack logic
ceph: don't release i_ceph_lock in handle_cap_trunc
ceph: don't take i_ceph_lock in handle_cap_import
ceph: document what protects i_dirty_item and i_flushing_item
ceph: fix potential race in ceph_check_caps
ceph: throw a warning if we destroy session with mutex still locked
ceph: convert mdsc->cap_dirty to a per-session list
ceph: request expedited service on session's last cap flush

Xiubo Li (6):
ceph: add dentry lease metric support
ceph: add caps perf metric for each superblock
ceph: add read/write latency metric support
ceph: add metadata perf metric support
ceph: make sure mdsc->mutex is nested in s->s_mutex to fix dead lock
ceph: skip checking caps when session reconnecting and releasing reqs
Yan, Zheng (1):
ceph: reset i_requested_max_size if file write is not wanted
