Subject: Revert "SELinux: Convert avc_audit to use lsm_audit.h"
X-Git-Tag: v2.6.32-rc1~737^2^2~46
X-Git-Url: http://ftp.safe.ca/?p=safe%2Fjmp%2Flinux-2.6;a=commitdiff_plain;h=be940d6279c30a2d7c4e8d1d5435f957f594d66d

Revert "SELinux: Convert avc_audit to use lsm_audit.h"

This reverts commit 8113a8d80f4c6a3dc3724b39b470f3fee9c426b6.

The patch causes a stack overflow on my system during boot.
