# With kernels 5.15 and newer be cautious of adding the option
# space_cache to the btrfs mount options. If the root volume is initially
# mounted with one version of space_cache and the mount option specifies
# a different version or implies v1 when v2 is in use, it may fail to
# remount properly.
# With kernels 5.15 and newer be cautious of adding the option space_cache
# to the btrfs mount options. The default in 5.15 changed to space_cache=v2.
# If space_cache or space_cache=v1 are specified, it may fail to remount.
