From 9f0e2acbdc7105f02a8cac2aa11cf9259dca34ae Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?John=20H=C3=B6gberg?= Date: Thu, 18 May 2017 23:05:02 +0200 Subject: Make lock counter info independent of the locks being counted This allows us to enable/disable lock counting at will, and greatly improves the performance of erts_debug:lock_counters/1 since we no longer have to worry about the lock counters "dying" while we're enumerating them.
