This patch adds a new test 255 that tests fallocate punch hole,
but is for use by generic filesystems. It is similar to 252,
but uses a weaker fiemap filter that only displays the location
of the hole, and not the extent types.

I realize Christoph already committed this but I
spotted something so I thought I might as well
mention it. I haven't tested any of this, so
it may be OK after all, but if it's not then
the filter_hole_fiemap() function ought to be
updated.

I believe this should be:
$5 ~ /0x[[:xdigit:]]+/ {
(I.e., hex digits, not just decimals.)
Hi Alex,
I think you are right. The extent flags are printed in hex, so it
should be xdigit. The existing _filter_fiemap routine that I modeled
this code from is also only parsing decimal digits. Even though the
tests are not showing any problems right now, it should probably be
fixed. Should I submit a patch to correct it?
