From: xiubli
Date: Tue Dec 13 2022 - 22:36:26 EST


From: Xiubo Li <xiubli@xxxxxxxxxx>

Changed in V5:
- s/fl_inode/inode/

Changed in V4:
- repeat the afs in fs.h instead of adding ceph specific header file

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 specific member support for file_lock
