ChenXiaoSong 5024878477 cifs: fix missing unlock in cifs_file_copychunk_range() ... xfstests generic/013 and generic/476 reported WARNING as follows: WARNING: lock held when returning to user space! 6.1.0-rc5+ #4 Not tainted ------------------------------------------------ fsstress/504233 is leaving the kernel with locks still held! 2 locks held by fsstress/504233: #0: ffff888054c38850 (&sb->s_type->i_mutex_key#21){+.+.}-{3:3}, at: lock_two_nondirectories+0xcf/0xf0 #1: ffff8880b8fec750 (&sb->s_type->i_mutex_key#21/4){+.+.}-{3:3}, at: lock_two_nondirectories+0xb7/0xf0 This will lead to deadlock and hungtask. Fix this by releasing locks when failed to write out on a file range in cifs_file_copychunk_range(). Fixes: 3e3761f1ec ("smb3: use filemap_write_and_wait_range instead of filemap_write_and_wait") Cc: stable@vger.kernel.org # 6.0 Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: ChenXiaoSong <chenxiaosong2@huawei.com> Signed-off-by: Steve French <stfrench@microsoft.com>		2022-11-21 10:27:03 -06:00
