iple openers don't make sense. Opening a floppy at
different densities with magic filenames was an example Linus used earlier
in the thread. Surely there can be more than one drive and more than one

It seems to me that Linus' idea of making device nodes work like
directories is a little too clever and probably overkill but the only
alternative I've seen suggested is Al's per-device filesystems which seems
similarly excessive.

Ok, I lied. Loo

Considering that the rest of the code is already in the standard kernel
and appears to work, there's no reason not to make it available.

My VAIO PCG-Z505SX locks up at "Uncompressing kernel", power cycling
required to reboot. Unpatched test12 works fine with same config. System
is debian-testing with gcc 2.95.2, kernel built with make-kpkg.
BTW, my USB camera (Canon S100), controlled through usbdevfs with gphoto2,
stopped working

Creating files with touch still works though. Persists after reboot,
forced e2fsck finds nothing wrong.
