Prev: [PATCH 07/38] whiteout: Set opaque flag if new directory was previously a whiteout
Next: [PATCH 13/38] fallthru: Basic fallthru definitions
From: Valerie Aurora on 6 Aug 2010 18:50
Major changes since last version:

* Separate MS_FALLTHRU instead of piggybacking on MS_WHITEOUT
* Renumbering of ext2 flags - backwards incompatible
* Bug fix for > 2 layers
* Better mount error messages (from Miklos Szeredi)
* Rebase against 2.6.35

This branch is named "ms_fallthru" and is in the usual git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/val/linux-2.6.git

You will have to update your util-linux-ng and e2fsprogs to get the
new magic numbers for ext2 feature flags and mount options. You have
to throw away any existing union mount ext2 disk images and build new
ones (all two of you who have them).

Branch "union_mount" of both:

git://git.kernel.org/pub/scm/fs/ext2/val/e2fsprogs.git

git://git.kernel.org/pub/scm/utils/util-linux-ng/val/util-linux-ng.git
