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 --- fs/namespace.c | 4 ++++ fs/notify/fsnotify.c | 4 +--- 2 files changed, 5 insertions(+), 3 deletions(-) (limited to 'fs') diff --git a/fs/namespace.c b/fs/namespace.c index 88058de59c7c..a2d681a6b5e9 100644 --- a/fs/namespace.c +++ b/fs/namespace.c @@ -29,6 +29,7 @@ #include #include #include +#include #include #include #include "pnode.h" @@ -150,6 +151,9 @@ struct vfsmount *alloc_vfsmnt(const char *name) INIT_LIST_HEAD(&mnt->mnt_share); INIT_LIST_HEAD(&mnt->mnt_slave_list); INIT_LIST_HEAD(&mnt->mnt_slave); +#ifdef CONFIG_FSNOTIFY + INIT_HLIST_HEAD(&mnt->mnt_fsnotify_marks); +#endif #ifdef CONFIG_SMP mnt->mnt_writers = alloc_percpu(int); if (!mnt->mnt_writers) diff --git a/fs/notify/fsnotify.c b/fs/notify/fsnotify.c index 60e84fd338dd..e0bf86953e1b 100644 --- a/fs/notify/fsnotify.c +++ b/fs/notify/fsnotify.c @@ -163,9 +163,7 @@ static bool needed_by_vfsmount(__u32 test_mask, struct vfsmount *mnt) if (!mnt) return false; - /* hook in this when mnt->mnt_fsnotify_mask is defined */ - /* return (test_mask & path->mnt->mnt_fsnotify_mask); */ - return false; + return (test_mask & mnt->mnt_fsnotify_mask); } /* * This is the main call to fsnotify.
