# Each dir contains one type of error for btrfsck test.
# Each dir must be one of the following 2 types:
# 1) Only btrfs-image dump
#    Only contains one or several btrfs-image dumps (.img)
#    Each image will be tested by generic test routine
#    (btrfsck --repair and btrfsck).
#    This is for case that btree-healthy images.
# 2) Custom test script
#    This dir contains test.sh which will do custom image
#    generation/check/verification.
#    This is for case btrfs-image can't dump or case needs extra
#    check/verify
