Hi ,
I tried  to install the patch  and maybe I missed something.
I copied  the information to a file named patch
then I  did
cd /usr/src
patch <   /root/patch
result was odd:
Hmmm... Looks like a unified diff to me...
The text leading up to this was:

File to patch:

Now what file do I want to patch or did I do something wrong?

Sincerely,
