From e40f9c8fac00476819d003bedbf899a52bbf09d1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?John=20H=C3=B6gberg?= Date: Wed, 1 Nov 2017 14:55:34 +0100 Subject: Remove all mention of efile_drv from DTrace docs efile_drv is gone and so is the need for file-specific DTrace. The new implementation works fine with the normal tracing mechanism so there's nothing preventing anyone from making an erl_tracer nif that forward these events to DTrace. --- lib/runtime_tools/examples/efile_drv.d | 105 ----------------------- lib/runtime_tools/examples/efile_drv.systemtap | 113 ------------------------- 2 files changed, 218 deletions(-) delete mode 100644 lib/runtime_tools/examples/efile_drv.d delete mode 100644 lib/runtime_tools/examples/efile_drv.systemtap (limited to 'lib/runtime_tools') diff --git a/lib/runtime_tools/examples/efile_drv.d b/lib/runtime_tools/examples/efile_drv.d deleted file mode 100644 index a470518dd9..0000000000 --- a/lib/runtime_tools/examples/efile_drv.d +++ /dev/null @@ -1,105 +0,0 @@ -/* example usage: dtrace -q -s /path/to/efile_drv.d */ -/* - * %CopyrightBegin% - * - * Copyright Scott Lystig Fritchie 2011-2016.
