[PATCH 3.13 009/120] audit: reset audit backlog wait time after error recovery

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Richard Guy Briggs <rgb@xxxxxxxxxx>

commit e789e561a50de0aaa8c695662d97aaa5eac9d55f upstream.

When the audit queue overflows and times out (audit_backlog_wait_time), the
audit queue overflow timeout is set to zero.  Once the audit queue overflow
timeout condition recovers, the timeout should be reset to the original value.
