Larry,
I have attached to this mail a pre-patch for linux-2.1.95/ncr53c8xx-2.5f
that tries to deal with SMP threading stuff as I would want the driver to
do.
The idea is to use 1 lock per controller instead of some more global
lock, assuming that SMP systems may often use several controllers.
I cannot try this patch under SMP as you know, but I did apply the
'non-regression tests' suggested by Linus and I can state that this
patch is perfect for UP. :-)
I will port the changes to 2.6i driver if they are reported as
correct and working.
Regards, Gerard.
PS: If SMP gurus could check the patch and let me know if it looks
correct, this would help me a lot. Thanks in advance.
