# Merge: 5b21115414f5b 3325322f773ba
# Author: Linus Torvalds <torvalds@linux-foundation.org>

# 
#     Merge tag 'ceph-for-5.6-rc1' of https://github.com/ceph/ceph-client
#     
#     Pull ceph fixes from Ilya Dryomov:
#     
#      - a set of patches that fixes various corner cases in mount and umount
#        code (Xiubo Li). This has to do with choosing an MDS, distinguishing
#        between laggy and down MDSes and parsing the server path.
#     
#      - inode initialization fixes (Jeff Layton). The one included here
#        mostly concerns things like open_by_handle() and there is another one
#        that will come through Al.
#     
#      - copy_file_range() now uses the new copy-from2 op (Luis Henriques).
#        The existing copy-from op turned out to be infeasible for generic
#        filesystem use; we disable the copy offload if OSDs don't support
#        copy-from2.
#     
#      - a patch to link "rbd" and "block" devices together in sysfs (Hannes
#        Reinecke)
#     
#     ... and a smattering of cleanups from Xiubo, Jeff and Chengguang.
#     
#     * tag 'ceph-for-5.6-rc1' of https://github.com/ceph/ceph-client: (25 commits)
#       rbd: set the 'device' link in sysfs
#       ceph: move net/ceph/ceph_fs.c to fs/ceph/util.c
#       ceph: print name of xattr in __ceph_{get,set}xattr() douts
#       ceph: print r_direct_hash in hex in __choose_mds() dout
#       ceph: use copy-from2 op in copy_file_range
#       ceph: close holes in structs ceph_mds_session and ceph_mds_request
#       rbd: work around -Wuninitialized warning
#       ceph: allocate the correct amount of extra bytes for the session features
#       ceph: rename get_session and switch to use ceph_get_mds_session
#       ceph: remove the extra slashes in the server path
#       ceph: add possible_max_rank and make the code more readable
#       ceph: print dentry offset in hex and fix xattr_version type
#       ceph: only touch the caps which have the subset mask requested
#       ceph: don't clear I_NEW until inode metadata is fully populated
#       ceph: retry the same mds later after the new session is opened
#       ceph: check availability of mds cluster on mount after wait timeout
#       ceph: keep the session state until it is released
#       ceph: add __send_request helper
#       ceph: ensure we have a new cap before continuing in fill_inode
#       ceph: drop unused ttl_from parameter from fill_inode
#       ...
