RE: kdump detection in SCSI drivers

["Mukker, Atul" <Atul.Mukker@lsi.com>]

How do we "know" when little memory is available?

Other suggestion which came about was to parse the kernel command line
and look for "elfcorehdr=". Is this ok? Is kernel command line visible
to the SCSI drivers?

Thanks

Perhaps you should be automatically using little resources when little
memory is available, or something? 

With upcomping kjump patches, it is more "interesting" than kdump
vs. no kdump.
