Subject: [PATCH 0/2 v3] ceph: fix the use-after-free bug for file_lock
From: Xiubo Li <xiubli@...hat.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
