Date: Thu, 06 Aug 2009 15:07:37 -0700 From: akpm@...ux-foundation.org To: torvalds@...ux-foundation.org Cc: akpm@...ux-foundation.org, sandeen@...hat.com, arnd@...db.de, jack@...e.cz, josef@...hat.com, linux-ext4@...r.kernel.org, lkml@....ca, stable@...nel.org Subject: [patch 07/15] compat_ioctl: hook up compat handler for FIEMAP ioctl From: Eric Sandeen <sandeen@...hat.com> 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.
