我们先看看i915_drv.c里面申明的driver变量：
static struct drm_driver driver = {

* deal with them for intel hardware.
*/
.driver_features =

很久没来博客了，这都拜公司那可恶的Websense所赐，最近时常发现有一些Linux命令莫名其妙的忘记了，也许是少用了，或者是老了：（于是想到索性在这里写一边文章记录一下，以便日后参考。
1、删除乱码文件：
# ll -i (获得文件节点号)
# find ./ -inum 节点号 -print -exec rm {} -rf \; (巧用find删除)
2、find与xargs� ......
