From: Miklos Szeredi <mszeredi@xxxxxxx> Reiserfs calls notify_change() on it's private extended attribute files to resize and change ownership of these files. Replace with reiserfs_setattr(). This is equivalent, except that: - i_alloc_sem locking is not performed around reiserfs_setattr() when the size is changed - security_inode_setattr() is not called before reiserfs_setattr() - fsnotify_change() is not called after reiserfs_setattr() None of the above is necessary, since the files are private to reiserfs and inaccessible from userspace. Also remove setting of ctime on the xattr files. Based on patch by Jeff Mahoney.
