Dear all,
(I think in particular Matt and Alex H.)

while porting drivers from FreeBSD some of us have stumbled over the functions
devfs_get_cdevpriv and devfs_set_cdevpriv, which store some
per-open-filedescriptor information for some devices.

I looked into the FreeBSD code and the implementation seems weird to me since
they store the filedescriptor on syscall in their thread struct and the 
functions
rely on that hidden state.

Question is now: Should we have similar functionality (i.e. per open
filedescriptor "private" data) and if yes how to best implement that. I know
that AlexH had made some suggestion but I cannot find it in the IRC logs and
it would probably be more efficient doing this by mail.
