Date: Fri, 18 Nov 2022 10:06:40 +0800 [thread overview]
Message-ID: <20221118020642.472484-1-xiubli@redhat.com> (raw)
From: Xiubo Li <xiubli@redhat.com>
Changed in V3:
- switched to vfs_inode_has_locks() helper to fix another ceph file lock
bug, thanks Jeff!
- this patch series is based on Jeff's previous VFS lock patch:
https://patchwork.kernel.org/project/ceph-devel/list/?series=695950
Changed in V2:
- switch to file_lock.fl_u to fix the race bug
- and the most code will be in the ceph layer
Xiubo Li (2):
ceph: switch to vfs_inode_has_locks() to fix file lock bug
ceph: add ceph_lock_info support for file_lock
