hi,
i was looking at the code of Floppy Driver by Linus, i was wondering the way
it has been coded !! even Linus has accepted that it can be further improved
a lot. i am thinking of making it more multithreaded, trying to find out the
details. any help on it would be highly appreciated.
thanx in advance.
Best Regards,
rajiv.

Uhm, it already is multithreaded. Kind Of. That is how a monolithic
kernel ends up working -- the exported floppy interface is threaded to
each running process that uses it. So each user space thread runs the
the kernel code in its context and you get a result of the floppy driver
being multithreaded.
Then you have the backend...the block and VM layers that obviously
aren't all in the context of a user space application. The system will
scale fine to your one floppy drive and multiple CPUs.
