Subject: xfs_io: fix test for fallocate on 32bit boxes
Date: Mon, 15 Jun 2009 14:43:04 -0500 [thread overview]
Message-ID: <4A36A448.4060406@sandeen.net> (raw)
xfs_io: fix test for fallocate on 32bit boxes
As per Red Hat bug 500487, fallocate64 is missing in glibc,
so attempts to build with fallocate and _FILE_OFFSET_BITS=64
will fail.
So, change the config to test the way we will build, and
it'll fail properly on x86 until glibc gets fixed.
