Merge tag 'ceph-for-5.9-rc1' of git://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "Xiubo has completed his work on filesystem client metrics, they are sent to all available MDSes once per second now. Other than that, we have a lot of fixes and cleanups all around the filesystem, including a tweak to cut down on MDS request resends in multi-MDS setups from Yanhu and fixups for SELinux symlink labeling and MClientSession message decoding from Jeff" * tag 'ceph-for-5.9-rc1' of git://github.com/ceph/ceph-client: (22 commits) ceph: handle zero-length feature mask in session messages ceph: use frag's MDS in either mode ceph: move sb->wb_pagevec_pool to be a global mempool ceph: set sec_context xattr on symlink creation ceph: remove redundant initialization of variable mds ceph: fix use-after-free for fsc->mdsc ceph: remove unused variables in ceph_mdsmap_decode() ceph: delete repeated words in fs/ceph/ ceph: send client provided metric flags in client metadata ceph: periodically send perf metrics to MDSes ceph: check the sesion state and return false in case it is closed libceph: replace HTTP links with HTTPS ones ceph: remove unnecessary cast in kfree() libceph: just have osd_req_op_init() return a pointer ceph: do not access the kiocb after aio requests ceph: clean up and optimize ceph_check_delayed_caps() ceph: fix potential mdsc use-after-free crash ceph: switch to WARN_ON_ONCE in encode_supported_features() ceph: add global total_caps to count the mdsc's total caps number ceph: add check_session_state() helper and make it global ...
