Looks like we have a bug in how we dump server name in some tracepoints e.g. see below: smfrench@smfrench-ThinkPad-P52:~/cifs-2.6$ sudo trace-cmd show # tracer: nop # # entries-in-buffer/entries-written: 1/1 #P:12 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | cifsd-82671 [006] .... 298870.051187: smb3_reconnect: conn_id=0x2 server=(0xffff950d5f6f6c00:localhost)[UNSAFE-MEMORY] current_mid=3105 -- Thanks, Steve
