怎样给内核打补丁？？

ida

升级后的内核为2.6.7，从www.kernel.org下载patch-2.6.8.bz2

# cp patch-2.6.8.bz2 /usr/src/linux-2.6.7
# bzip2 -dc patch-2.6.8.bz2 | patch -p0

等待一会儿后，就出现了：

[root@AMD-SERVER root]# bzip2 -dc patch-2.6.8.bz2 | patch -p0
can't find file to patch at input line 4
Perhaps you used the wrong -p or --strip option?
The text leading up to this was:
--------------------------
|diff -Nru a/CREDITS b/CREDITS
|--- a/CREDITS  2004-08-13 22:39:03 -07:00
|+++ b/CREDITS  2004-08-13 22:39:03 -07:00
--------------------------

这里应该怎样继续下去？

晨想

cd /usr/src/linux-2.6.7
