Subject: [PATCH 13/22] /dev/random: kill extract_timer_state
Date: Thu, 25 Mar 2004 17:57:44 -0600 [thread overview]
Message-ID: <14.524465763@selenic.com> (raw)
In-Reply-To: <13.524465763@selenic.com>
/dev/random kill extract_timer_state
Remove unused extract_timer_state struct. It was formerly used to
feedback zero-entropy timing samples while extracting entropy, but
that had a tendency to overwhelm the batch processing queue and
prevent storing real samples.
