From 4f572f0074b8be8a70bd150d96a749aa94c8d85f Mon Sep 17 00:00:00 2001 From: Haibo Li haibo.li@mediatek.com Date: Fri, 26 May 2023 10:21:25 +0800 Subject: [PATCH] mm/gup_test: fix ioctl fail for compat task
When tools/testing/selftests/mm/gup_test.c is compiled as 32bit, then run on arm64 kernel, it reports "ioctl: Inappropriate ioctl for device".
Fix it by filling compat_ioctl in gup_test_fops
