This looks almost almost exactly the same test as 242 just with the
alloc, map and punch commands changed. I'd suggest making all these
cases into a function that takes three parameters - alloc_cmd
punch_cmd and map_cmd - and pulling it into common.punch.
e.g. we end up with a function full of commands like:
$XFS_IO_PROG -F -f -c "truncate 20k" \
-c "$punch_cmd 4k 8k" \
-c "$map_cmd" $testfile | _filter_bmap
Which means it can be used for 242, this test, and another test for
the xfs resvsp/unresvsp ioctls...
Cheers,
Dave.
