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:
Run btrfs subvolume create/mount/umount/delete and remount with
different compress algorithms simultaneously, with fsstress running

btrfs fileystem show and btrfs device scan today both have
the -d option to scan everything under /dev. But we also
have a mechanism to scan everything in /proc/partitions, which
should always be sufficient.
If anyone knows why we'd find something deep under /dev but
not in /proc/partitions,
We can scan for btrfs devices in a few ways. By default
libblkid is used for device scan and filesystem show;
with the -m option only mounted filesystems are scanned,
and with -d we physically read every system device.
But there's no reason for the complexity of a descent through
/dev;
After the previous 2 patches, nothing uses
whole-dev-tree scanning, so remove the code which
implemented that functionality.
