When you take a lock in a debugfs handler but also try to remove the debugfs file under that lock, things can deadlock since the removal has to wait for all users to finish. Add lockdep annotations in debugfs_file_get()/_put() to catch such issues. Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Johannes Berg <johannes.berg@intel.com> |
