From 26245c949c8473ea7352907b5a54bc34487eb87f Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Wed, 6 Jan 2010 17:20:35 +0100 Subject: quota: Cleanup S_NOQUOTA handling Cleanup handling of S_NOQUOTA inode flag and document it a bit. The flag does not have to be set under dqptr_sem. Only functions modifying inode's dquot pointers have to check the flag under dqptr_sem before going forward with the modification. This way we are sure that we cannot add new dquot pointers to the inode which is just becoming a quota file. The good thing about this cleanup is that there are no more places in quota code which enforce i_mutex vs. dqptr_sem lock ordering (in particular that dqptr_sem -> i_mutex of quota file). This should silence some (false) lockdep warnings with ext4 + quota and generally make life of some filesystems easier.

So make Q_XQUOTASYNC call into the writeback code directly and make the quota_sync method optional as XFS doesn't need in the sense expected by the rest of the quota code. GFS2 was using limited XFS-style quota and has a quota_sync method fitting neither the style used by vfs_quota_sync nor xfs_fs_quota_sync. I left it in for now as per discussion with Steve it expects to be called from the sync path this way.

Grabbing the reference on the superblock really isn't much overhead for a global Q_SYNC call, so just drop this optimization.

Also get rid of the vfs_dq_alloc/vfs_dq_free wrappers and always call the lowlevel dquot_alloc_inode / dqout_free_inode routines directly, which now lose the number argument which is always 1.

This means we tie the quota code into the VFS. Get rid of that and make the filesystem responsible for the transfer. Most filesystems already do this, only ufs and udf need the code added, and for jfs it needs to be enabled unconditionally instead of only when ACLs are enabled.

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.

Rename the now static low-level dquot_initialize helper to __dquot_initialize and vfs_dq_init to dquot_initialize to have a consistent namespace.
