Ahh yes. So you'll see here that there's a new build for you not yet in updates

Don't know. btrfs-progs 3.16 is current in

I don't see a -m option for btrfs restore, maybe use --path-regex instead.
I just did this without the script and it worked:
1. mkfs.btrfs /dev/sdc
2. mount /dev/sdc /mnt
3. mkdir /mnt/pics
4. scp IMG_3327.tif :/mnt/pics/

This patchset add new stress test cases for btrfs by running two
different btrfs operations simultaneously under fsstress to ensure
btrfs doesn't hang or oops in such situations. btrfs scrub and
btrfs check will be run after each test.
The test matrix is the combination of 6 btrfs operations:

Hi,
When I ran a stress test for Btrfs (v3.17-rc2), then I got the following
warning messages repeatedly. I think the messages were outputted because
btrfs_block_rsv_migrate() returned as ENOSPC.
I'm not sure this is related to a bug or not...
How to reproduce:
1. Create btrfs on a 5GB partition
