commit df9aa2ce436132568b8f94e9d69e63992d2bf779
Author: Mark Wielaard <>
Date:   Sat Nov 12 22:30:28 2011 +0100

    sched_switch.stp parse arguments once, workaround name argument WARNINGs.
    stap got smarter and now detects some arguments aren't used or used
    "wrongly". Add a begin probe to parse the arguments, use strtol if
    necessary, and add usage message in case wrong number of args were given.
    This suppresses WARNINGs for 'stap sched_switch.stp name firefox':
    WARNING: never-assigned local variable 'firefox' (alternatives: __tracepoint_arg_p name task task_pid task_tid task_priority task_cpu task_state): identifier 'firefox' at testsuite/systemtap.examples/profiling/sched_switch.stp:34:19
     source:                if (task_pid != $2 && pid() != $2)
    WARNING: never-assigned local variable 'firefox' (alternatives: __tracepoint_arg_prev __tracepoint_arg_next next_pid next_tid next_task next_task_name nexttsk_state next_priority prev_priority prev_pid prev_tid prev_task prev_task_name prevtsk_state name): identifier 'firefox' at :53:19
