From c2fbaa4b489b738cd9e7666edfeceaaa38e71c9f Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Thu, 25 Feb 2010 03:03:52 +0100 Subject: [PATCH] perf/scripts: Tag syscall_name helper as not yet available syscall_name() helper, which resolves a syscall arch number to its name, is not yet available as we first need to implement event injection for it to work. Remove it from the documentation or tag its references as unavailable yet. Once it's implemented, we can just revert the current patch.
