^^^^^^^^^^^^^^^^
this doesn't look correct to me, the "bracket expression" is a
"Character Classes", grep matches any single char in the char set. A
quick test shows it only matches the last two chars, that's "n]"
$ echo "[offset len]" | grep "[offset [len]]"
[offset len]
^^ highlighted
fgrep should work, or grep -q "\[offset \[len\]\]"
But now the fiemap check in _require_xfs_io_command checks range support
on whatever $param it takes, even the '[-al] [-n nx]' param that have
nothing to do with range.
Thanks,
