2009-01-09filesystem freeze: add error handling of write_super_lockfs/unlockfsTakashi Sato1-4/+6
Currently, ext3 in mainline Linux doesn't have the freeze feature which suspends write requests. So, we cannot take a backup which keeps the filesystem's consistency with the storage device's features (snapshot and replication) while it is mounted. In many case, a commercial filesystem (e.g. VxFS) has the freeze feature and it would be used to get the consistent backup. If Linux's standard filesystem ext3 has the freeze feature, we can do it without a commercial filesystem. So I have implemented the ioctls of the freeze feature. I think we can take the consistent backup with the following steps. 1. Freeze the filesystem with the freeze ioctl. 2. Separate the replication volume or create the snapshot with the storage device's feature. 3. Unfreeze the filesystem with the unfreeze ioctl. 4. Take the backup from the separated replication volume or the snapshot. This patch: VFS: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they can return an error. Rename write_super_lockfs and unlockfs of the super block operation freeze_fs and unfreeze_fs to avoid a confusion. ext3, ext4, xfs, gfs2, jfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that write_super_lockfs returns an error if needed, and unlockfs always returns 0. reiserfs: Changed the type of write_super_lockfs and unlockfs from "void" to "int" so that they always return 0 (success) to keep a current behavior.

2008-11-14CRED: Wrap task credential accesses in the JFS filesystemDavid Howells1-2/+2
Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

This is a much better version of a previous patch to make the parser tables constant.

2008-01-03JFS is missing a memory barrierNick Piggin1-2/+2
JFS is missing a memory barrier needed to close the critical section before clearing the lock bit. Use lock bitops for this. unlock_page() has a second barrier after clearing the lock, which is required because it checks whether the waitqueue is active without locks. Such a barrier is not required here because the waitqueue spinlock is always taken (something to think about if performance is an issue).

2008-01-03JFS: clear PAGECACHE_TAG_DIRTY for no-write pagesDave Kleikamp1-3/+8
When JFS decides to drop a dirty metapage, it simply clears the META_dirty bit and leave alone the PG_dirty and PAGECACHE_TAG_DIRTY bits. When such no-write page goes to metapage_writepage(), the `relic' PAGECACHE_TAG_DIRTY tag should be cleared, to prevent pdflush from repeatedly trying to sync them. This is done through set_page_writeback(), so call it should be called in all cases. If no I/O is initiated, end_page_writeback() should be called immediately. This is how __block_write_full_page() does things. Signed-off-by: Dave Kleikamp <shaggy@linux.vnet.ibm.com> CC: Fengguang Wu <wfg@mail.ustc.edu.cn>
