From 84047e360af0394ac5861d433f26bbcf30f77dd1 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Tue, 2 Jun 2009 16:51:55 -0400 Subject: [PATCH] function-graph: always initialize task ret_stack On creating a new task while running the function graph tracer, if we fail to allocate the ret_stack, and then fail the fork, the code will free the parent ret_stack. This is because the child duplicated the parent and currently points to the parent's ret_stack. This patch always initializes the task's ret_stack to NULL. [ Impact: prevent crash of parent on low memory during fork ] Signed-off-by: Steven Rostedt --- Reading git-format-patch failed
