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
