OK..I've had one instance of this so far, and this is somewhat of a
religious issue for me, so I'm adding a quick note here. These
pre-patches
and the real patches (when done) are adding new files to the linux
source code tree. There is a well known problem with the patch program
and new files when you don't use the -p option to the patch program. So
here's the recommendation from a kernel hacker on the correct, painless,
religiously tolerable :) method of using patch:
1. Always cd *into* the kernel directory you wish to patch. This way,
if you didn't make your kernel directory named linux, or someone's
patch wasn't made against files in a directory called linux, there
won't be a problem because you are in the directory you want to
be in.
2. While you are there, use the patch program with the switches -p1 and
-E. The -p1 tells the patch program you went on into the 1st
directory and that should be stripped from the filenames in the
patch, and the -E tells patch to remove those files that are totally
empty when the patch is done.
There, follow those two rules, and patching will go very smooth in the
future for you :)
