From a082f872743e09fe2cdf870b2d8f1b5dccd36cf7 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Wed, 29 Jan 2014 16:05:30 -0500 Subject: [PATCH] Btrfs: disable snapshot aware defrag for now 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.
