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. - -- Marcin Krzysztof Porwit mporwit@centeris.com #include -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGGseV4OZU6cX5VBERAjceAJ9IPuMxujrzRCMHmQLuwj1lIerAUgCeOdCh ymMgN+KqAo0Gzya3iihgtBw= =TSXw -----END PGP SIGNATURE-----
