| * ext3/jbd: Avoid WARN() messages when failing to write the superblockDarrick J. Wong2010-10-281-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a WARN backtrace in mark_buffer_dirty() that occurs during unmount when the underlying block device is removed. This bug has been seen on System Z when removing all paths from a multipath-backed ext3 mount; on System P when injecting enough PCI EEH errors to make the SCSI controller go offline; and similar warnings have been seen (and patched) with ext2/ext4. The super block update from a previous operation has marked the buffer as in error, and the flag has to be cleared before doing the update. Similar changes have been made to ext4 by commit 914258bf2cb22bf4336a1b1d90c551b4b11ca5aa. Signed-off-by: Darrick J. Wong <djwong@us.ibm.com> Signed-off-by: Jan Kara <jack@suse.cz>
| * ext3: Fix lost extented attributes for inode with ino == 11Jan Kara2010-10-051-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a filesystem has inode size > 128 and someone deletes lost+found and reuses inode 11 for some other file, extented attributes set for this inode before umount will get lost after remounting the filesystem. This is because extended attributes will get stored in an inode but ext3_iget will ignore them due to workaround of a bug in an old mkfs. Fix the problem by initializing i_extra_isize to 0 for freshly allocated inodes where mkfs workaround in ext3_iget applies. This way these inodes will always store extended attributes in a special block and no problems occur.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | All the blkdev_issue_* helpers can only sanely be used for synchronous caller. To issue cache flushes or barriers asynchronously the caller needs to set up a bio by itself with a completion callback to move the asynchronous state machine ahead. So drop the BLKDEV_IFL_WAIT flag that is always specified when calling blkdev_issue_* and also remove the now unused flags argument to blkdev_issue_flush and blkdev_issue_zeroout. For blkdev_issue_discard we need to keep it for the secure discard flag, which gains a more descriptive name and loses the bitops vs flag confusion.

It explicitly adds calls to lock_kernel()/unlock_kernel() around get_sb/fill_super operations for filesystems that still uses the BKL. I've read through all the code formerly covered by the BKL inside do_kern_mount() and have satisfied myself that it doesn't need the BKL any more. do_kern_mount() is already called without the BKL when mounting the rootfs and in nfsctl. do_kern_mount() calls vfs_kern_mount(), which is called from various places without BKL: simple_pin_fs(), nfs_do_clone_mount() through nfs_follow_mountpoint(), afs_mntpt_do_automount() through afs_mntpt_follow_link(). Both later functions are actually the filesystems follow_link inode operation. vfs_kern_mount() is calling the specified get_sb function and lets the filesystem do its job by calling the given fill_super function. Therefore I think it is safe to push down the BKL from the VFS to the low-level filesystems get_sb/fill_super operation.

* | ext3: Fix dirtying of journalled buffers in data=journal modeJan Kara2010-08-051-1/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In data=journal mode, we still use block_write_begin() to prepare page for writing. This function can occasionally mark buffer dirty which violates journalling assumptions - when a buffer is part of a transaction, it should be dirty and a buffer can be already part of a forget list of some transaction when block_write_begin() gets called. This violation of journalling assumptions then results in "JBD: Spotted dirty metadata buffer..." warnings. In fact, temporary dirtying the buffer while the page is still locked does not really cause problems to the journalling because we won't write the buffer until the page gets unlocked. So we just have to make sure to clear dirty bits before unlocking the page. Reviewed-by: "Theodore Ts'o" <tytso@mit.edu> Signed-off-by: Jan Kara <jack@suse.cz>

Thus if we crash before a transaction clearing the block pointer is committed, we will see indirect block pointing to already freed blocks and complain during orphan list cleanup.

| * quota: unify quota init condition in setattrDmitry Monakhov2010-05-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Quota must being initialized if size or uid/git changes requested. But initialization performed in two different places: in case of i_size file system is responsible for dquot init , but in case of uid/gid init will be called internally in dquot_transfer(). This ambiguity makes code harder to understand. Let's move this logic to one common helper function. Signed-off-by: Dmitry Monakhov <dmonakhov@openvz.org> Signed-off-by: Jan Kara <jack@suse.cz>
| * ext3: make barrier options consistent with ext4Eric Sandeen2010-05-211-7/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ext4 was updated to accept barrier/nobarrier mount options in addition to the older barrier=0/1. The barrier story is complex enough, we should help people by making the options the same at least, even if the defaults are different. This patch allows the barrier/nobarrier mount options for ext3, while keeping nobarrier the default. It also unconditionally displays barrier status in show_options, and prints a message at mount time if barriers are not enabled, just as ext4 does.

| * ext3: Fix waiting on transaction during fsyncJan Kara2010-05-211-11/+9
| | | | | | | | | | | | | | | | | | | | log_start_commit() returns 1 only when it started a transaction commit. Thus in case transaction commit is already running, we fail to wait for the commit to finish. Fix the issue by always waiting for the commit regardless of the log_start_commit return value.

| * ext3: init statistics after journal recovery v2Dmitry Monakhov2010-05-211-23/+21
| | | | | | | | | | | | | | | | | | | | Currently block/inode/dir counters are initialized before journal was recovered. In fact after journal recovery this info will probably change which results in incorrect numbers returned from statfs(2).

| * ext3: Avoid loading bitmaps for full groups during block allocationFrans van de Wiel2010-05-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | There is no point in loading bitmap for groups which are completely full. This causes noticeable performance problems (and memory pressure) on small systems with large full filesystem (http://marc.info/?l=linux-ext4&m=126843108314310&w=2).
