I removed the redundant #unconditional and added tests for fs_info,
after fixing preexisting tests which were already failing. The
preexisting and new tests are optional and are only run when a valid
btrfs fd is provided; tests/btrfs-w.test shows how that works with

I tested with something like this:

# setup
dd if=/dev/zero of=./btrfs.img bs=4k count=100000
mkfs.btrfs ./btrfs.img # apt-get install btrfs-progs
sudo losetup /dev/loop0 ./btrfs.img
sudo mount -t btrfs ./btrfs.img /mnt

# test
sudo BTRFS_MOUNTPOINT=/mnt make check \
  TESTS='btrfs-X btrfs-v btrfs-vX btrfs-vw btrfs-vwX btrfs-w btrfs-wX'

# cleanup
sudo umount /mnt
sudo losetup -d /dev/loop0
rm ./btrfs.img
