From 26c01624a2a40f8a4ddf6449b65c9b1c418d0e72 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 2 Jun 2009 14:01:19 -0400 Subject: [PATCH] function-graph: add memory barriers for accessing task's ret_stack The code that handles the tasks ret_stack allocation for every task assumes that only an interrupt can cause issues (even though interrupts are disabled). In reality, the code is allocating the ret_stack for tasks that may be running on other CPUs and there are not efficient memory barriers to handle this case. [ Impact: prevent crash due to using of uninitialized ret_stack variables ] Signed-off-by: Steven Rostedt --- Reading git-format-patch failed
