Hi Linus, The following changes since commit 7111951b8d4973bda27ff663f2cf18b663d15b48: Linux 5.6 (2020-03-29 15:25:41 -0700) are available in the Git repository at: https://github.com/ceph/ceph-client.git tags/ceph-for-5.7-rc1 for you to fetch changes up to ef9157259fb7bb3bc2c61df227e36f1b861a4753: ceph: fix snapshot directory timestamps (2020-03-30 12:42:43 +0200) ---------------------------------------------------------------- The main items are: - 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) ---------------------------------------------------------------- Andreas Gruenbacher (1): ceph: switch to page_mkwrite_check_truncate in ceph_page_mkwrite Gustavo A. R. Silva (1): ceph: replace zero-length array with flexible-array member Hannes Reinecke (2): rbd: kill img_request kref rbd: enable multiple blk-mq queues Ilya Dryomov (7): libceph: drop CEPH_DEFINE_SHOW_FUNC rbd: remove barriers from img_request_layered_{set,clear,test}() rbd: get rid of img_request_layered_clear() rbd: acquire header_rwsem just once in rbd_queue_workfn() rbd: embed image request in blk-mq pdu libceph: simplify ceph_monc_handle_map() libceph: directly skip to the end of redirect reply Jeff Layton (18): ceph: register MDS request with dir inode from the start ceph: add refcounting for Fx caps ceph: don't ClearPageChecked in ceph_invalidatepage() ceph: reorganize fields in ceph_mds_request ceph: move to a dedicated slabcache for mds requests ceph: clean up kick_flushing_inode_caps() ceph: more caps.c lockdep assertions ceph: add flag to designate that a request is asynchronous ceph: track primary dentry link ceph: add infrastructure for waiting for async create to complete ceph: make __take_cap_refs non-static ceph: cap tracking for async directory operations ceph: perform asynchronous unlink if we have sufficient caps ceph: make ceph_fill_inode non-static ceph: decode interval_sets for delegated inos ceph: add new MDS req field to hold delegated inode number ceph: cache layout in parent dir on first sync create ceph: attempt to do async create when possible Luis Henriques (2): ceph: re-org copy_file_range and fix some error paths ceph: fix snapshot directory timestamps Qiujun Huang (1): ceph: return ceph_mdsc_do_request() errors from __get_parent() Xiubo Li (3): ceph: move ceph_osdc_{read,write}pages to ceph.ko ceph: fix description of some mount options ceph: return ETIMEDOUT errno to userland when request timed out Yan, Zheng (14): ceph: check inode type for CEPH_CAP_FILE_{CACHE,RD,REXTEND,LAZYIO} ceph: check if file lock exists before sending unlock request ceph: don't take refs to want mask unless we have all bits ceph: update dentry lease for async create ceph: always renew caps if mds_wanted is insufficient ceph: consider inode's last read/write when calculating wanted caps ceph: remove delay check logic from ceph_check_caps() ceph: simplify calling of ceph_get_fmode() ceph: update i_requested_max_size only when sending cap msg to auth mds ceph: check all mds' caps after page writeback ceph: cleanup return error of try_get_cap_refs() ceph: request new max size only when there is auth cap ceph: don't skip updating wanted caps when cap is stale ceph: wait for async creating inode before requesting new max size Documentation/filesystems/ceph.txt | 6 +- drivers/block/rbd.c | 215 ++++++--------- fs/ceph/addr.c | 90 ++++++- fs/ceph/cache.c | 2 +- fs/ceph/caps.c | 536 ++++++++++++++++++++----------------- fs/ceph/debugfs.c | 16 +- fs/ceph/dir.c | 132 ++++++++- fs/ceph/export.c | 5 + fs/ceph/file.c | 486 +++++++++++++++++++++++++-------- fs/ceph/inode.c | 84 +++--- fs/ceph/ioctl.c | 2 + fs/ceph/locks.c | 31 ++- fs/ceph/mds_client.c | 240 ++++++++++++++--- fs/ceph/mds_client.h | 30 ++- fs/ceph/super.c | 28 ++ fs/ceph/super.h | 70 +++-- include/linux/ceph/ceph_fs.h | 18 +- include/linux/ceph/debugfs.h | 14 - include/linux/ceph/libceph.h | 1 + include/linux/ceph/osd_client.h | 17 -- net/ceph/debugfs.c | 20 +- net/ceph/mon_client.c | 8 +- net/ceph/osd_client.c | 82 ------ 23 files changed, 1380 insertions(+), 753 deletions(-)
