-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

I'm trying to find examples of the kernel doing a non-blocking upcall to
userspace while processing a request. None of the kernel books really
get into this, so I'm hoping someone can just point me at an existing
example.

In this case, what I'm looking to do is call up to winbindd to get some
credentials for a user while the kernel is handling a mount request.

Thanks for any info.
