fs: Remove ext3 filesystem driver The functionality of ext3 is fully supported by ext4 driver. Major distributions (SUSE, RedHat) already use ext4 driver to handle ext3 filesystems for quite some time. There is some ugliness in mm resulting from jbd cleaning buffers in a dirty page without cleaning page dirty bit and also support for buffer bouncing in the block layer when stable pages are required is there only because of jbd. So let's remove the ext3 driver. This saves us some 28k lines of duplicated code. Acked-by: Theodore Ts'o <tytso@mit.edu> Signed-off-by: Jan Kara <jack@suse.cz>

ext4: Use ext4 file system driver for ext2/ext3 file system mounts Add a new config option, CONFIG_EXT4_USE_FOR_EXT23 which if enabled, will cause ext4 to be used for either ext2 or ext3 file system mounts when ext2 or ext3 is not enabled in the configuration. This allows minimalist kernel fanatics to drop to file system drivers from their compiled kernel with out losing functionality. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>

ext4: fix configuration dependencies for ext4 ACLs and security labels Commit "ext4: Remove CONFIG_EXT4_FS_XATTR" removed the configuration dependencies for ext4 xattrs from the ext4 ACLs and security labels configuration options, but did not replace them with a dependency on ext4 itself. Add back the dependency on ext4 so the options only show up if ext4 is enabled.
