From 10f471b97d403e236bc23db91d4c3b3395d7ccd8 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Thu, 6 Aug 2009 15:07:37 -0700 Subject: compat_ioctl: hook up compat handler for FIEMAP ioctl commit 69130c7cf96ea853dc5be599dd6a4b98907d39cc upstream. The FIEMAP_IOC_FIEMAP mapping ioctl was missing a 32-bit compat handler, which means that 32-bit suerspace on 64-bit kernels cannot use this ioctl command. The structure is nicely aligned, padded, and sized, so it is just this simple. Tested w/ 32-bit ioctl tester (from Josef) on a 64-bit kernel on ext4.
