Jan Kara a80b12c3d0 quota: Get rid of nested I_MUTEX_QUOTA locking subclass ... So far i_mutex was ranking above dqonoff_mutex and i_mutex on quota files was special and ranking below dqonoff_mutex (and several other locks). However there's no real need for i_mutex on quota files to be special. IO on quota files is serialized by dqio_mutex anyway so we don't need to take i_mutex when writing to quota files. Other places where we take i_mutex on quota file can accomodate standard i_mutex lock ranking, we only need to change the lock ranking to be dqonoff_mutex > i_mutex which is a matter of changing documentation because there's no place which would enforce ordering in the other direction.
