MegaRAID driver version 2.00.7 is released and can be download from
ftp://ftp.lsil.com/pub/linux-megaraid/drivers/version-2.00.7/
Changes from 2.00.6:
i. Adapter lock re-definition so that patch for kernels w/o per host
lock
is less intrusive - Jens Axboe <[email protected]>
ii. While in abort and reset handling, check for non-empty pending list
is
invalid. The intent is to wait for pending commands in FW to
complete,
not the pending commands with the driver - Atul Mukker

But all kernels do not have this lock as part of the host structure. With
2.00.7, I have relapsed a patch which switches the lock to io_request_lock
if kernel does not support per host lock.
And not all kernels have the per host lock named as "host->host_lock", some
simply have "host->lock"

All 2.5/2.6 kernels do have host->host_lock and the 2.5 driver is different
from the 2.4 one. In fact it will hopefuloly become &host->host_lock soon
but for that I have to repair the remaining abusers first.

Right, in next patch for 2.6 I will take care of this..
