# Test the unsupported fallocate flags on a block device. No collapse
# or insert range, no regular fallocate, no forgetting keep-space on
# zero range, no punching past EOD, no requests that aren't aligned
# with the logicalsector size, and make sure the fallbacks work for
# devices that don't support write_same or discard.
