FC6 kernel source missing AACRAID source

[ocgltd]

I have a fresh FC6 install, and want to upgrade the kernel module for the Adaptec Raid controller. I have done this with a FC5 install and everything worked great, but in FC6 there is a problem.

I downloaded the latest kernel source, and changed to the /usr/src/linux/drivers/scsi/aacraid directory. But this directory is EMPTY (other than a Makefile). Where is the source for the aacraid driver?

I know the module for this driver is in the kernel because modinfo shows an old version running.

1. Can someone help me find it?
2. Can I simply copy the updated driver source (including Makefile) into this directory and rebuild the kernel modules?

Thanks,
MD
