As Chris Mason mentioned, fixed in the following patch:

That should probably go to -stable (if it hasn't already), especially as 3.14
is a new LTS kernel.
cheers,

Wang,
Yes that certainly helps me make more sense of it. I was able to get the
qgroup assigning to work properly.
I guess the next question would be if it would be a valid feature to
implement automatic qgroup deletion

the cause is that it only frees @fs_devices but leaves it on the global

As a point of reference, my BTRFS filesystem with 11 x 21TB devices in
RAID0 with space cache enabled takes about 4 minutes to mount after a
clean unmount.
There is a decent amount of variation in the amount of time (has been as
low as 3 minutes or taken 5 minutes or longer). These devices

Hi, the following patches try to fix a long outstanding issue with qgroups
and snapshot deletion. The core problem is that btrfs_drop_snapshot will
skip shared extents during it's tree walk. This results in an inconsistent
qgroup state once the drop is processed.
The first patch adds some tracing
During its tree walk, btrfs_drop_snapshot() will skip any shared
subtrees it encounters. This is incorrect when we have qgroups
turned on as those subtrees need to have their contents
accounted. In particular, the case we're concerned with is when
removing our snapshot root leaves the subtree with
From: Josef Bacik jba...@fb.com
Before I extended the no_quota arg to btrfs_dec/inc_ref because I didn't
understand how snapshot delete was using it and assumed that we needed the
quota operations there. With Mark's work this has turned out to be not the
case, we _always_ need to use no_quota
