From e0ccfd959cd8907bcb66cc2042e0f4fd7fcbff2b Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 19 May 2010 07:16:42 -0400 Subject: quota: move unmount handling into the filesystem Currently the VFS calls into the quotactl interface for unmounting filesystems. This means filesystems with their own quota handling can't easily distinguish between user-space originating quotaoff and an unount. Instead move the responsibily of the unmount handling into the filesystem to be consistent with all other dquot handling. Note that we do call dquot_disable a lot later now, e.g. after a sync_filesystem. But this is fine as the quota code does all its writes via blockdev's mapping and that is synced even later.
