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 Signed-off-by: NIngo Molnar <mingo@elte.hu> Signed-off-by: NJens Axboe <jens.axboe@oracle.com>
