This patch defines a common helper function to test whether any of
fsxattr xflags field is set or not. We will use this helper in the next
patch for checking extsize (e) flag.

Better to explain the arguments, e.g.

That's too complex. Those "return" aren't needed as Darrick metioned. About
that two "grep", how about combine them, e.g.

_test_xfs_xflags_field()
{
	grep -q "fsxattr.xflags.*\[.*$2.*\]" <($XFS_IO_PROG -c "stat" "$1")
}

Is this really necessary? Will this test fail without this line?
The common/$FSTYP file is imported automatically, if it's not, that a bug.
If the generic helper goes in common/rc instead then it's not necessary
at all.
Won't the "_source_specific_fs $FSTYP" in common/rc helps to import common/xfs?
Yeah, it gets imported automatically(I have verified). Anyway, I am moving the helper function to common/rc, so this won't be required.

Thanks,
