From 2868201965419b9011f3f07fd80e765181343cb1 Mon Sep 17 00:00:00 2001 From: Eric Paris Date: Thu, 28 Oct 2010 17:21:56 -0400 Subject: fanotify: use __aligned_u64 in fanotify userspace metadata Currently the userspace struct exposed by fanotify uses __attribute__((packed)) to make sure that alignment works on multiarch platforms. Since this causes a severe performance penalty on some platforms we are going to switch to using explicit alignment notation on the 64bit values so we don't have to use 'packed' Signed-off-by: Eric Paris --- include/linux/fanotify.h | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/linux/fanotify.h b/include/linux/fanotify.h index 2c89ce7b644e..8a621c1a0991 100644 --- a/include/linux/fanotify.h +++ b/include/linux/fanotify.h @@ -79,10 +79,10 @@ struct fanotify_event_metadata { __u32 event_len; __u32 vers; - __u64 mask; + __aligned_u64 mask; __s32 fd; __s32 pid; -} __attribute__ ((packed)); +}; struct fanotify_response { __s32 fd; -- cgit v1.2.3
