I could use a hand applying a patch to the kernel source. I'm attempting
to apply the "low-latency" patch. (http://people.redhat.com/mingo/lowlatency-patches/)
I have the kernel source in /usr/src/linux and the patch at
/usr/src/lowlatency-2.2.16-A0
I've been typing various mutations of
cd /usr/src/linux
patch /usr/src/lowlatency-2.2.16-A0 -p0

patch -p 0 < /usr/src/lowlatency-2.2.16-A0
One note - this may or may not work well with kernel sources provided by a distribution. RedHat in particularly doesn't distribute the standard sources but rather just the architecture specific portions + patches. Getting clean sources from ftp.kernel.org may be necessary.

I was able to patch the kernel once I had the proper instructions, thanks
to Karl. I patched and it compiled fine. What I would like to find is a way to check if there is any benefit to running a low latency patched kernel. Although the topic of latency has come up now and again on the PD list, I'm not sure how much of a benefit it offers to PD users. I'm guessing that it would be useful to people that are doing a lot of disk reads and writes.
