Eliminate now-unused SUSER_ALLOWJAIL arguments to priv_check_cred(); in 2007-06-12T00:12:01+00:00 Robert Watson rwatson@FreeBSD.org 2007-06-12T00:12:01+00:00 32f9753cfbfe844fa6c02c88c7ca96617e903d8e some cases, move to priv_check() if it was an operation on a thread and no other flags were present. Eliminate caller-side jail exception checking (also now-unused); jail privilege exception code now goes solely in kern_jail.c. We can't yet eliminate suser() due to some cases in the KAME code where a privilege check is performed and then used in many different deferred paths. Do, however, move those prototypes to priv.h.
