Hello,

I have been unable to patch my kernel, I am a noob at this and the 
method i used a few months ago to apply Srinivas patches for mvsas does 
not work now. I have asked for help from my distro (arch linux), but if 
you have a quick and easy way for me to patch sas_ata.c and reload the 
module without reboots or complete kernel recompilations I would be 
grateful to hear it.

Kind regards
