    Subject[PATCH 0/5] tracing: seqfile fixes
    While testing syscall tracepoints proposed by Jason, I found some
    entries were missing when reading available_events.

    It turned out there's bug in seqfile handling. The bug is, it's
    wrong to increment @pos in seq start().

    I fixed similar bugs in some other places. (the last patch fixes
    a different seqfile bug)

    [PATCH 1/5] tracing/events: don't increment @pos in s_start()
    [PATCH 2/5] tracing_bprintk: don't increment @pos in t_start()
    [PATCH 3/5] trace_stat: don't increment @pos in stat_seq_start()
    [PATCH 4/5] ftrace: don't increment @pos in g_start()
    [PATCH 5/5] tracing: reset iterator in t_start()
