From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eric Sandeen Subject: [PATCH] hook up compat handler for FIEMAP ioctl Date: Mon, 27 Jul 2009 15:09:22 -0500 Message-ID: <4A6E0972.5010803@redhat.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit To: ext4 development , linux-fsdevel Return-path: Sender: linux-ext4-owner@vger.kernel.org List-Id: linux-fsdevel.vger.kernel.org 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.
