fsnotify: Remove useless list deletion and comment
After removing all the indirection it is clear that hlist_del_init_rcu(&mark->obj_list); in fsnotify_destroy_marks() is not needed as the mark gets removed from the list shortly afterwards in fsnotify_destroy_mark() -> fsnotify_detach_mark() -> fsnotify_detach_from_object(). Also there is no problem with mark being visible on object list while we call fsnotify_destroy_mark() as parallel destruction of marks from several places is properly handled (as mentioned in the comment in fsnotify_destroy_marks(). So just remove the list removal and also the stale comment. Reviewed-by: Miklos Szeredi <mszeredi@redhat.com> Reviewed-by: Amir Goldstein <amir73il@gmail.com> Signed-off-by: Jan Kara <jack@suse.cz>
