Merge tag 'ceph-for-5.1-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "The highlights are: - rbd will now ignore discards that aren't aligned and big enough to actually free up some space (myself). This is controlled by the new alloc_size map option and can be disabled if needed. - support for rbd deep-flatten feature (myself). Deep-flatten allows "rbd flatten" to fully disconnect the clone image and its snapshots from the parent and make the parent snapshot removable. - a new round of cap handling improvements (Zheng Yan). The kernel client should now be much more prompt about releasing its caps and it is possible to put a limit on the number of caps held. - support for getting ceph.dir.pin extended attribute (Zheng Yan)" * tag 'ceph-for-5.1-rc1' of git://github.com/ceph/ceph-client: (26 commits) Documentation: modern versions of ceph are not backed by btrfs rbd: advertise support for RBD_FEATURE_DEEP_FLATTEN rbd: whole-object write and zeroout should copyup when snapshots exist rbd: copyup with an empty snapshot context (aka deep-copyup) rbd: introduce rbd_obj_issue_copyup_ops() rbd: stop copying num_osd_ops in rbd_obj_issue_copyup() rbd: factor out __rbd_osd_req_create() rbd: clear ->xferred on error from rbd_obj_issue_copyup() rbd: remove experimental designation from kernel layering ceph: add mount option to limit caps count ceph: periodically trim stale dentries ceph: delete stale dentry when last reference is dropped ceph: remove dentry_lru file from debugfs ceph: touch existing cap when handling reply ceph: pass inclusive lend parameter to filemap_write_and_wait_range() rbd: round off and ignore discards that are too small rbd: handle DISCARD and WRITE_ZEROES separately rbd: get rid of obj_req->obj_request_count libceph: use struct_size() for kmalloc() in crush_decode() ceph: send cap releases more aggressively ...
