    [PATCH] blktrace: add timestamp message · be1c6341
    Olaf Kirch 提交于
    This adds a new timestamp message to blktrace, giving the timeofday when
    we starting tracing. This helps user space correlate block trace events
    with eg an application strace.
    
    This requires a (compatible) update to blkparse. The changed blkparse
    is still able to process traces generated by older kernels, and older
    versions of blkparse should silently ignore the new records (because
    they have a pid of 0).
