[PATCH 3.11 009/121] Btrfs: disable snapshot aware defrag for now

[Luis Henriques]

3.11.10.5 -stable review patch.  If anyone has any objections, please let me know.

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

From: Josef Bacik <jbacik@xxxxxx>

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,
