Is there any way to call a user-space function from within a kernel module,
providing at some point a function pointer was passed in? If so how would
you call this function if you were in the context of another process?

Hello!
In article <AEEEJLJGDLODKEHHFIABMECPCFAA.kwooten@home.com> you write:

No precise hints, but you could look at the way how signal handler
functions are called.
Another way is to avoid the problem, using instead a userland<->kernel
socket (or similar) connection and some "remote procedure call" over
that socket.
Hope that helps a bit.
Kind regards,
Hannah.
