* dquot: cleanup space allocation / freeing routinesChristoph Hellwig2010-03-04
| | | | | | | | | | | | | | | | Get rid of the alloc_space, free_space, reserve_space, claim_space and release_rsv dquot operations - they are always called from the filesystem and if a filesystem really needs their own (which none currently does) it can just call into it's own routine directly. Move shared logic into the common __dquot_alloc_space, dquot_claim_space_nodirty and __dquot_free_space low-level methods, and rationalize the wrappers around it to move as much as possible code into the common block for CONFIG_QUOTA vs not. Also rename all these helpers to be named dquot_* instead of vfs_dq_*. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jan Kara <jack@suse.cz>

* jfs: Fix early release of acl in jfs_get_aclStefan Bader2009-07-23
| | | | | | | | | | | | | | | | | | | | BugLink: http://bugs.launchpad.net/ubuntu/+bug/396780 Commit 073aaa1b142461d91f83da66db1184d7c1b1edea "helpers for acl caching + switch to those" introduced new helper functions for acl handling but seems to have introduced a regression for jfs as the acl is released before returning it to the caller, instead of leaving this for the caller to do. This causes the acl object to be used after freeing it, leading to kernel panics in completely different places. Thanks to Christophe Dumez for reporting and bisecting into this.

| * jfs: fix regression preventing coalescing of extentsDave Kleikamp2009-06-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit fec1878fe952b994125a3be7c94b1322db586f3b caused a regression in which contiguous blocks being allocated to the end of an extent were getting a new extent created. This typically results in files entirely made up of 1-block extents even though the blocks are contiguous on disk. Apparently grub doesn't handle a jfs file being fragmented into too many extents, since it refuses to boot a kernel from jfs that was created by the 2.6.30 kernel.

* proc 2/2: remove struct proc_dir_entry::ownerAlexey Dobriyan2009-03-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy as correctly noted at bug #12454. Someone can lookup entry with NULL ->owner, thus not pinning enything, and release it later resulting in module refcount underflow. We can keep ->owner and supply it at registration time like ->proc_fops and ->data. But this leaves ->owner as easy-manipulative field (just one C assignment) and somebody will forget to unpin previous/pin current module when switching ->owner. ->proc_fops is declared as "const" which should give some thoughts. ->read_proc/->write_proc were just fixed to not require ->owner for protection. rmmod'ed directories will be empty and return "." and ".." -- no harm. And directories with tricky enough readdir and lookup shouldn't be modular. We definitely don't want such modular code. Removing ->owner will also make PDE smaller. So, let's nuke it. Kudos to Jeff Layton for reminding about this, let's say, oversight. http://bugzilla.kernel.org/show_bug.cgi?id=12454 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com>

* | filesystem freeze: add error handling of write_super_lockfs/unlockfsTakashi Sato2009-01-09
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
