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 ...
