ocfs2: Use __dquot_transfer to avoid lock inversion
dquot_transfer() acquires own references to dquots via dqget(). Thus it waits for dq_lock which creates a lock inversion because dq_lock ranks above transaction start but transaction is already started in ocfs2_setattr(). Fix the problem by passing own references directly to __dquot_transfer. Acked-by: Joel Becker <Joel.Becker@oracle.com> Signed-off-by: Jan Kara <jack@suse.cz>
