ext3

ext3 adds journaling filesystem capabilities to ext2fs.

What is journaling?

It means you don't have to fsck after a crash. Basically.

What works?

Journaling to a journal file on the journaled filesystem
Automatic recover when the filesystem is remounted
All VFS operations (including quota) should be journaled
Add data updates are also journaled

What is left to be done?

Quota support for non-data-journaled filesystems.
Journaling to an off-filesystem device, eg. NVRam
Decent documentation!
A few internal cleanups: migrating the extra buffer_head fields to a separate jfs_buffer_info field in particular.
