ext4: add missing unlock to an error path in ext4_quota_write()

2008-07-04T17:40:05+00:00

When write in ext4_quota_write() fails, we have to properly release
i_mutex.  One error path has been missing the unlock...

ext4: enable barriers by default

2008-05-26T16:29:46+00:00

I can't think of any valid reason for ext4 to not use barriers when
they are available;  I believe this is necessary for filesystem
integrity in the face of a volatile write cache on storage.

An administrator who trusts that the cache is sufficiently battery-
backed (and power supplies are sufficiently redundant, etc...)
can always turn it back off again.

SuSE has carried such a patch for ext3 for quite some time now.

Also document the mount option while we're at it.

jbd2: If a journal checksum error is detected, propagate the error to ext4

2008-06-06T21:50:40+00:00

If a journal checksum error is detected, the ext4 filesystem will call
ext4_error(), and the mount will either continue, become a read-only
mount, or cause a kernel panic based on the superblock flags
indicating the user's preference of what to do in case of filesystem
corruption being detected.

ext4: fix synchronization of quota files in journal=data mode

2008-05-13T23:11:51+00:00

In journal=data mode, it is not enough to do write_inode_now as done in
vfs_quota_on() to write all data to their final location (which is
needed for quota_read to work correctly).  Calling journal_flush() does
its job.

ext4: Fix mount messages when quota disabled

2008-05-13T23:11:51+00:00

When quota is disabled, we should not print 'journaled quota not
supported' when user tried to mount non-journaled quota. Also fix typo
in the message.

ext4: correct mount option parsing to detect when quota options can be changed

2008-05-13T23:11:51+00:00

We should not allow user to change quota mount options when quota is
just suspended.  It would make mount options and internal quota state
inconsistent.  Also we should not allow user to change quota format when
quota is turned on.  On the other hand we can just silently ignore when
some option is set to the value it already has (mount does this on
remount).

ext4: don't use ext4_error in ext4_check_descriptors

2008-04-30T02:00:28+00:00

Because ext4_check_descriptors is called at mount time you can't use ext4_error
as it calls ext4_commit_sb, which since the sb isn't all the way initialized
causes bad things to happen (ie a panic).  This patch changes the ext4_error's
to printk's to keep this problem from happening.  Thanks much,

ext4: move headers out of include/linux

2008-04-29T22:13:32+00:00

Move ext4 headers out of include/linux.  This is just the trivial move,
there's some more thing that could be done later.
