mbcache: Remove unused features

2010-08-09T20:48:45Z

The mbcache code was written to support a variable number of indexes, but all the existing users use exactly one index. Simplify to code to support only that case. There are also no users of the cache entry free operation, and none of the users keep extra data in cache entries. Remove those features as well.

dquot: cleanup space allocation / freeing routines

2010-03-04T23:20:28Z

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 Signed-off-by: Jan Kara

ext3: Use bitops to read/modify EXT3_I(inode)->i_state

2010-03-04T23:20:20Z

At several places we modify EXT3_I(inode)->i_state without holding i_mutex (ext3_release_file, ext3_bmap, ext3_journalled_writepage, ext3_do_update_inode, ...). These modifications are racy and we can lose updates to i_state. So convert handling of i_state to use bitops which are atomic. Signed-off-by: Jan Kara

sanitize xattr handler prototypes

2009-12-16T17:16:49Z

Add a flags argument to struct xattr_handler and pass it to all xattr handler methods. This allows using the same methods for multiple handlers, e.g. for the ACL methods which perform exactly the same action for the access and default ACLs, just using a different underlying attribute. With a little more groundwork it'll also allow sharing the methods for the regular user/trusted/secure handlers in extN, ocfs2 and jffs2 like it's already done for xfs in this patch. Also change the inode argument to the handlers to a dentry to allow using the handlers mechnism for filesystems that require it later, e.g. cifs.

ext3: journal all modifications in ext3_xattr_set_handle

2009-12-10T14:02:52Z

ext3_xattr_set_handle() was zeroing out an inode outside of journaling constraints; this is one of the accesses that was causing the crc errors in journal replay as seen in kernel.org bugzilla #14354. Although ext3 doesn't have the crc issue, modifications out of journal control are a Bad Thing. Signed-off-by: Eric Sandeen Signed-off-by: Jan Kara

ext3/4: fix uninitialized bs in ext3/4_xattr_set_handle()

2008-05-15T02:11:14Z

This fix the uninitialized bs when we try to replace a xattr entry in ibody with the new value which require more than free space. This situation only happens we format ext3/4 with inode size more than 128 and we have put xattr entries both in ibody and block. The consequences about this bug is we will lost the xattr block which pointed by i_file_acl with all xattr entires in it. We will alloc a new xattr block and put that large value entry in it. The old xattr block will become orphan block. Signed-off-by: Tiger Yang Cc: Cc: Andreas Gruenbacher Acked-by: Andreas Dilger Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
