ftrace_graph_ret_addr() now returns the passed in return address when NULL is passed for the 'idx' paramenter. This breaks the current usage in csky's walk_stackframe()
Fix this by passing a valid integer pointer to ftrace_graph_ret_addr() Signed-off-by: Puranjay Mohan <[email protected]> --- arch/csky/kernel/stacktrace.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/arch/csky/kernel/stacktrace.c b/arch/csky/kernel/stacktrace.c index 27ecd63e321b..1d72f18064c2 100644 --- a/arch/csky/kernel/stacktrace.c +++ b/arch/csky/kernel/stacktrace.c @@ -17,6 +17,7 @@ void notrace walk_stackframe(struct task_struct *task, struct pt_regs *regs, bool (*fn)(unsigned long, void *), void *arg) { unsigned long fp, sp, pc; + int graph_idx = 0; if (regs) { fp = frame_pointer(regs); @@ -50,7 +51,7 @@ void notrace walk_stackframe(struct task_struct *task, struct pt_regs *regs, frame = (struct stackframe *)fp; sp = fp; fp = frame->fp; - pc = ftrace_graph_ret_addr(current, NULL, frame->ra, + pc = ftrace_graph_ret_addr(current, &graph_idx, frame->ra, (unsigned long *)(fp - 8)); } } -- 2.40.1
