From 5cf8cf4146de03de67d1a8aefbece66b65f255cc Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 26 Feb 2009 21:32:51 +0100 Subject: Fix FREEZE/THAW compat_ioctl regression Commit 8e961870bb9804110d5c8211d5d9d500451c4518 removed the FREEZE/THAW handling in xfs_compat_ioctl but never added any compat handler back, so now any freeze/thaw request from a 32-bit binary ond 64-bit userspace will fail. As these ioctls are 32/64-bit compatible two simple COMPATIBLE_IOCTL entries in fs/compat_ioctl.c will do the job.
