MRG current has a very old megaraid_sas driver

=Comment: #0================================================= John G. Stultz <johnstul@us.ibm.com> - So we were trying to bring up MRG on a new box, and ran into trouble when the megaraid sas driver wasn't seeming to find the controller. All we got with kernel-rt-2.6.24.7-146.el5rt.x86_64.rpm was: ----------------------------------------------------------- megasas: 00.00.03.16-rc1 Thu.

Talked w/ Chris McDermott and he magically knew what commit *should* fix this: git show 6610a6b354d6c3377a1e79cd1d760ffe4358245c Any chance that this commit could be added?
*** Bug 554681 has been marked as a duplicate of this bug. ***
Patch bz554664-scsi-megaraid_sas-add-new-controllers-0x78-0x79.patch, backport of upstream commit 6610a6b354d6c3377a1e79cd1d760ffe4358245c, has been added to kernel 2.6.24.7-247.el5rt patch queue.
------- Comment From johnstul@us.ibm.com 2010-01-18 16:11 EDT------- Rob has tested the -147 kernel with the system in question and it did boot up. I think we can mark this resolved.

This sounds indeed like wonderful news! I don't mean to be a party killer, but have you done any stress tests with this driver? I would just like to be sure that we don't regress on both performance and reliability. After all it's a new controller card which now is supported, which probably means a different firmware and so on.
Verified by code review. Found patch mentioned in comment #2 applied to kernel-rt-2.6.24.7-149.src.rpm.
