I've dropped the async unlink patch from testing branch and am resubmitting it here along with the rest of the create patches. Zheng had pointed out that DIR_* caps should be cleared when the session is reconnected. The underlying submission code needed changes to handle that so it needed a bit of rework (along with the create code). Since v3: - rework async request submission to never queue the request when the session isn't open - clean out DIR_* caps, layouts and delegated inodes when session goes down - better ordering for dependent requests - new mount options (wsync/nowsync) instead of module option - more comprehensive error handling Jeff Layton (9): ceph: add flag to designate that a request is asynchronous ceph: perform asynchronous unlink if we have sufficient caps ceph: make ceph_fill_inode non-static ceph: make __take_cap_refs non-static ceph: decode interval_sets for delegated inos ceph: add infrastructure for waiting for async create to complete 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 fs/ceph/caps.c | 73 +++++++--- fs/ceph/dir.c | 101 +++++++++++++- fs/ceph/file.c | 253 +++++++++++++++++++++++++++++++++-- fs/ceph/inode.c | 58 ++++---- fs/ceph/mds_client.c | 156 +++++++++++++++++++-- fs/ceph/mds_client.h | 17 ++- fs/ceph/super.c | 20 +++ fs/ceph/super.h | 21 ++- include/linux/ceph/ceph_fs.h | 17 ++- 9 files changed, 637 insertions(+), 79 deletions(-) -- 2.24.1
