From 2504c5d63b811b71bbaa8d5d5af163e698f4df1f Mon Sep 17 00:00:00 2001 From: Andreas Gruenbacher Date: Thu, 17 Dec 2009 21:24:27 -0500 Subject: fsnotify/vfsmount: add fsnotify fields to struct vfsmount This patch adds the list and mask fields needed to support vfsmount marks. These are the same fields fsnotify needs on an inode. They are not used, just declared and we note where the cleanup hook should be (the function is not yet defined) Signed-off-by: Andreas Gruenbacher Signed-off-by: Eric Paris --- include/linux/mount.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'include/linux/mount.h') diff --git a/include/linux/mount.h b/include/linux/mount.h index 4bd05474d11d..907210bd9f9c 100644 --- a/include/linux/mount.h +++ b/include/linux/mount.h @@ -56,7 +56,11 @@ struct vfsmount { struct list_head mnt_mounts; /* list of children, anchored here */ struct list_head mnt_child; /* and going through their mnt_child */ int mnt_flags; - /* 4 bytes hole on 64bits arches */ + /* 4 bytes hole on 64bits arches without fsnotify */ +#ifdef CONFIG_FSNOTIFY + __u32 mnt_fsnotify_mask; + struct hlist_head mnt_fsnotify_marks; +#endif const char *mnt_devname; /* Name of device e.g. /dev/dsk/hda1 */ struct list_head mnt_list; struct list_head mnt_expire; /* link in fs-specific expiry list */ -- cgit v1.2.3 From 532490f0a5350fd92d838b7430a4c846bc8eac3f Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 2 Aug 2010 13:46:56 +0200 Subject: vfs: remove unused MNT_STRICTATIME Commit d0adde574b8487ef30f69e2d08bba769e4be513f added MNT_STRICTATIME but it isn't actually used (MS_STRICTATIME clears MNT_RELATIME and MNT_NOATIME rather than setting any mount flag).
