From c54143281596a7757786057e759ed08ec482aae4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn-Egil=20Dahlberg?= Date: Thu, 11 Dec 2014 16:56:13 +0100 Subject: tools: Fix lcnt sort of inspected locks An error was introduced in commit f24d1ad9004b2885cd3b15ac0bf9d1407ca68bc8 which reversed the sorting of all locks. This meant that the least contended locks was printed instead of the most contended. This commit reverses the reverse. --- lib/tools/src/lcnt.erl | 34 ++++++++++++++++++---------------- 1 file changed, 18 insertions(+), 16 deletions(-) diff --git a/lib/tools/src/lcnt.erl b/lib/tools/src/lcnt.erl index f1251fddab..5b125c6f5a 100644 --- a/lib/tools/src/lcnt.erl +++ b/lib/tools/src/lcnt.erl @@ -305,7 +305,7 @@ handle_call({inspect, Lockname, InOpts}, _From, #state{ duration=Duration, locks {true, true} -> locks_ids(Filtered);
