Stack tracing with ftrace does currently not work properly when trace-cmd is used on x86_64 machines -- only half of each stack entry is shown (things work fine with the ftrace debugfs interface):
mutextest-7604 [001] 664.978289: user_stack: => (000000002a7ac565) => (000000002a7a6070) => (00000000ffffffff)
The following two patches modify the kernel to use the proper trace_printk format, and fix trace_cmd to parse the format correctly:
mutextest-7604 [001] 664.978289: user_stack: => (00007f342a7ac565) => (00007f342a7a6070) => (ffffffffffffffff)
Cheers, Wolfgang
