Jan Kara 7d6cd73d33 quota: Hold s_umount in exclusive mode when enabling / disabling quotas ... Currently we hold s_umount semaphore only in shared mode when enabling or disabling quotas and use dqonoff_mutex for serializing quota state changes on a filesystem and also quota state changes with other places depending on current quota state. Using dedicated mutex for this causes possible deadlocks during filesystem freezing (see following commit for details) so we transition to using s_umount semaphore for the necessary synchronization whose lock ordering is properly handled by the filesystem freezing code. As a start grab s_umount in exclusive mode when enabling / disabling quotas. Signed-off-by: Jan Kara <jack@suse.cz>		2016-11-24 15:26:53 +01:00
