linux raid patch

[John Barbee]

I'm running Redhat 6 which comes with the 2.2.5 kernel.

Does that mean I should be using the raid0145-2.2.6 patch from ftp.kernel.org?

How do I incorporate this patch into the kernel.  I couldn't find any
directions.  The patch starts with a lot of +'s and -'s.  I presume those
mark the differences between what the block_device.c file is and what it
should be, but what is the proper way for me to update that file?
