Subject: [PATCH 0/2] Fix misuse of blk_rq_stats in blk-iolatency

From: Pavel Begunkov <asml.silence@...il.com>

There are implicit assumptions about struct blk_rq_stats, which make
it's very easy to misuse. The first patch fixes consequences, and the
second employs type-system to prevent recurrences.


Pavel Begunkov (2):
  blk-iolatency: Fix zero mean in previous stats
  blk-stats: Introduce explicit stat staging buffers
