From 7dbdee2e9a2ac42ea5135801bcc9d1a8e3f672aa Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 6 Aug 2009 19:53:18 -0400 Subject: tracing: Fix recordmcount.pl to handle sections with only weak functions Roland Dreier found that a section that contained only a weak function in one of the staging drivers and this caused recordmcount.pl to spit out a warning and fail. Although it is strange that a driver would have a weak function, and this function only be used in one place, it should not be something to make recordmcount.pl fail. This patch fixes the issue in a simple manner: if only weak functions exist in a section, then that section will not be recorded.
