2.6.30-stable review patch. If anyone has any objections, please let us know. ------------------ From: Eric Sandeen <sandeen@xxxxxxxxxx> 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.
