From f3fa8288287072195baa791ee11d5480d3cd45ff Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?John=20H=C3=B6gberg?= Date: Thu, 22 Jun 2017 13:22:13 +0200 Subject: Allow toggling lock counting at runtime The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will.
