From 257ba15cedf1288f0c96118d7e63947231d27278 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Wed, 3 Mar 2010 09:05:04 -0500 Subject: dquot: move dquot drop responsibility into the filesystem Currently clear_inode calls vfs_dq_drop directly. This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the drop inside the ->clear_inode superblock operation.

This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the initialization. For most metadata operations this is a straight forward move into the methods, but for truncate and open it's a bit more complicated. For truncate we currently only call vfs_dq_init for the sys_truncate case because open already takes care of it for ftruncate and open(O_TRUNC) - the new code causes an additional vfs_dq_init for those which is harmless. For open the initialization is moved from do_filp_open into the open method, which means it happens slightly earlier now, and only for regular files. The latter is fine because we don't need to initialize it for operations on special files, and we already do it as part of the namespace operations for directories. Add a dquot_file_open helper that filesystems that support generic quotas can use to fill in ->open.
