Subject: [PATCH] hook up compat handler for FIEMAP ioctl
Date: Mon, 27 Jul 2009 15:09:22 -0500 [thread overview]
Message-ID: <4A6E0972.5010803@redhat.com> (raw)
The FIEMAP_IOC_FIEMAP mapping ioctl was missing a 32-bit
compat handler; the structure is nicely aligned, padded,
and sized, so it should be just this simple.
Tested w/ 32-bit ioctl tester (from Josef) on a 64-bit
kernel on ext4.
