Subject[PATCH 3.10 02/26] Btrfs: disable snapshot aware defrag for now
Date
3.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Josef Bacik <jbacik@fb.com>

commit 8101c8dbf6243ba517aab58d69bf1bc37d8b7b9c upstream.

It's just broken and it's taking a lot of effort to fix it, so for now just
disable it so people can defrag in peace. Thanks,
