Megaraid does not work with 2.4.22

I don't know what is the opinion of other people :-? Maybe linux-scsi members hold other opinion.
Well I for example would be more than pleased to see megaraid 2.x included in the next stable 2.4.x Linux kernel !! I had a look at the current changelogs of 2.4.23 and still no traces about a megaraid v2 inclusion :(( Hopefully that will happen soon !
Regards

Having two drivers for the same controller is not a good thing from a user point of view. I just asked Atul privately but will do so again here: Why do we need "megaraid2" ?

this doesn't is first time:

megaraid 1.xx gets *very bad* performance. But like 2.4 is stable serie, it shouldn't be deleted.
megaraid 2.xx gets correct performance, it's stable and it adds support for _present_ hardware, MegaRAID Ultra320 RAID boards(518, 520, 531, 532).
-thanks-

Fine. I agree on adding in to mainline 2.4.x.

Here go some trivial fixes(add menu entry, list all compatibles boards in help and put tab instead spaces) for megaraid2.

This is a patch against 2.4.22-bk30, and it's
necessary to be able to compile megaraid2 and to
get help text from menuconfig.

Xose is correct. His patch should indeed be applied to the latest bk tree so the megaraid2 driver can actually be compiled into 2.4.x.
