Block layer?I remember initially there are three types of device
drivers, say, char device driver, block device driver, network device
driver, so there is a
ic. thanks a lot for explanation.
so these are level sensitive interrupt.
i need to find a hw book now...

i tried to remove the SA_SHIRQ option when request_irq(), unfortunately
it seems that the IO-APIC will only try to allocate same # to it and
once that slot is used, the request_irq will fail.

we tested several iSCSI initiator/target combinations that work with
2TB devices in current 2.6.11.x kernel.

u are talking about application aware caching/prefetching stuff. but i
prefer to modifying kernel page cache a little bit while make use of
most of the code there.
That's a powerful argument for using the page cache, and further, for
