It should apply against 2.4.1 or 2.4.1-acXX kernels. Note that it

Hi,
Is it possible to download a drive firmware to a fibre channel
drive (or even a scsi drive) through linux ? I know that on
NT (or 98) they use WNASPI and a utility provided by the
drive manufacturer to download the firmware. I was wondering
if this is possible through linux scsi interface. F

No, if you enlarge the hash table twice (and re-hash everything) every time the
table fills up, the load factor of the table keeps small and everything is O(1)

The one change which is probably causing this is non-critical,
so let me study things quickly tonight and if I come up with
nothing I'll show you what you can revert safely.

Yep.
