Re: [PATCH] audit: allow unlimited backlog queue

Since audit can already be disabled by "audit=0" on the kernel boot line, or by the command "auditctl -e 0", it would be more useful to have the audit_backlog_limit set to zero mean effectively unlimited (limited only by system resources). Signed-off-by: Richard Guy Briggs <rgb(a)redhat.com&gt; --- Steve, These are userspace source code documentation changes in what's going in upstream.
