[PATCH 6.1 204/236] btrfs: add missing mutex_unlock in btrfs_relocate_sys_chunks()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


6.1-stable review patch.  If anyone has any objections, please let me know.


From: Dominique Martinet <dominique.martinet@xxxxxxxxxxxxxxxxx>

commit 9af503d91298c3f2945e73703f0e00995be08c30 upstream.

The previous patch that replaced BUG_ON by error handling forgot to
unlock the mutex in the error path.
