Subject: [PATCH 0/2] Fix ftrace stack traces on x86_64
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
