" From: Joshua Boyd <jdboyd at jdboyd.net>
" When I have trouble with either USB or CIFS, the rest of the machine is
" fully usable, so I can potentially put off a reboot for awhile, but I
" must do it eventually if I want to use either service again.
" THAT makes me with that USB and CIFS were userland services. Of course,
" that would potentially cause a performance hit. As it stands, I believe
" you would have both multiple data copies and multiple context switches.
" In theory, something could probably be done to make going between two
" userland processes like that zero copy, but I don't know how you would
" get around the context switches.
if linux had lkm like solaris, you could just unload/reload the
offending driver... i've almost got it down to a script for
/dev/audio, except fuser won't show processes using it, which have to
be killed before it will unload.
