Not to even suggest a 100% cleanliness, but simply
as a matter of incremental improvements here's one
simple idea.
Wouldn't the approach of treating #X as channels
instead of full fledged parallel namespace be at least
somewhat cleaner than what we have today? If the only
thing that any of the "#X" permitted was to issue a
mount/bind syscall, it would, IMHO, simplify and
clean at least the following areas:
1.1. the need for less than ideal special case in
namec():
switch(name[0]){
case '#':
Not that we would get rid of it 100%, but it seems
much more appropriate in bindmount()
1.2. the need for an implicit and poorly documented
and thus confusing ->attach in namec():
switch(name[0]){
case '#':
.....
c = devtab[t]->attach(up->genbuf+n);
1.3. an ability of userspace applications to bypass
the venerable namespace mechanics
The above seems like a net gain, doesn't it?
Thanks,
Roman.
