[Devel] RE: [SCSI] 3w-9xxx: kmap_atomic in twa_scsiop_execute_scsi

[Adam Radford]

Vasily,

I actually didn't forget this.  I think it isn't needed.  The reason
being
that in scsi.c: scsi_dispatch_command(), where hostt->queuecommand() is
called,
there is a spin_lock_irqsave()/spin_unlock_irqrestore() wrapper in
there, disabling
interrupts.

Hello Adam,

you have fixed recently potential memory corruption, kmap_atomic issue
in 3w-9xxx driver, however it seems for me you have forgotten to fix the
same issue in yet another similar place, in twa_scsiop_execute_scsi()
function.
