# Now do the actual test. We can turn on and off append (a), compressed (c),

# attribute flags. The following associations can be seen:
#
# chattr flag stx_attributes flag
# +a STATX_ATTR_APPEND
# +c STATX_ATTR_COMPRESSED
# +d STATX_ATTR_NODUMP
# +i STATX_ATTR_IMMUTABLE
#
# Note, however, that if the filesystem doesn't paste this information into
# stx_attributes, there's no way to tell the difference between cleared and
# unset.
