Currently compiling block/blk-settings.c with C=1 gives the following warning: block/blk-settings.c:262:9: warning: context imbalance in 'queue_limits_commit_update' - wrong count at exit request_queue.limits_lock is a mutex. Sparse locking annotation for mutexes are currently not supported - see [0] - so drop that locking annotation.
