From 583f34c493fc5b91aa05a8987023244a72f8efae Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Thu, 11 Apr 2019 19:53:45 +0200 Subject: [PATCH] Declare -realtime as deprecated The old -realtime mlock=on|off parameter does exactly the same as the new -overcommit mem-lock=on|off parameter. Additionally, "-realtime" does not activate any additional "realtime" capabilities as the name might indicate. We should avoid to confuse the users this way, so let's deprecate the old -realtime option.
