This one should have been dropped (per http://lkml.org/lkml/2008/1/25/413)
I don't like rq->clock relying on jiffies, and you already fixed the
original manifestation of the problem in:

    block: fix blktrace timestamps

    David Dillow reported broken blktrace timestamps. The reason
    is cpu_clock() which is not a global time source.

    Fix bkltrace timestamps by using ktime_get() like the networking
    code does for packet timestamps. This also removes a whole lot
    of complexity from bkltrace.c and shrinks the code by 500 bytes:

       text    data     bss     dec     hex filename
       2888     124      44    3056     bf0 blktrace.o.before
       2390     116      44    2550     9f6 blktrace.o.after
