Just to keep everyone up to date, here is a third iteration of
my patch converting devfs to a ramfs-based file system. This one uses
an almost unmodified version of devfs/util.c to restore automatic
device number allocation and devfs_{,un}register_tape().
This code now tries to implement almost all of the devfs
functionality that anything outside of arch/ia64/sn uses. The most
significant except that I'm aware of is the ability to create a plain
file with custom file operations, which is done the Memory Type Range
Register code, but that code also provides a proc interface for the
same thing, and I think the proc interface is what everyone uses right
now anyhow.
If Christoph's patch for deleting a bunch of unused stuff from
devfs gets into 2.5.54, that should make my patch smaller, and I'll
post a new version then. If nobody objects, then perhaps I'll make
that version replace fs/devfs rather than creating a separate
fs/mini-devfs.
