Merge tag 'ceph-for-6.11-rc1' of https://github.com/ceph/ceph-client
Pull ceph updates from Ilya Dryomov: "A small patchset to address bogus I/O errors and ultimately an assertion failure in the face of watch errors with -o exclusive mappings in RBD marked for stable and some assorted CephFS fixes" * tag 'ceph-for-6.11-rc1' of https://github.com/ceph/ceph-client: rbd: don't assume rbd_is_lock_owner() for exclusive mappings rbd: don't assume RBD_LOCK_STATE_LOCKED for exclusive mappings rbd: rename RBD_LOCK_STATE_RELEASING and releasing_wait ceph: fix incorrect kmalloc size of pagevec mempool ceph: periodically flush the cap releases ceph: convert comma to semicolon in __ceph_dentry_dir_lease_touch() ceph: use cap_wait_list only if debugfs is enabled
