From f95732e2e0a649c148be0242b72e3c7473092687 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Mon, 10 Sep 2012 23:31:17 -0700 Subject: audit: kill audit_prepare_user_tty Now that netlink messages are processed in the context of the sender tty_audit_push_task can be called directly and audit_prepare_user_tty which only added looking up the task of the tty by process id is not needed.
