2017-12-11mmc_test: use ktime_get_ts64 for timestampsArnd Bergmann
Calling getnstimeofday() can suffer from time jumps and from the y2038 overflow, so it is not appropriate here. Using ktime_get_ts64() solves both problems. Using ktime_get() with ktime_t timestamps would also work, but it seems that we mainly want to print the times as seconds+nanoseconds, so it would require an extra division in the output.

There are only a few things the recovery needs to do. Primarily, it just needs to: Determine the number of bytes transferred Get the card back to transfer state Determine whether to retry There are also a couple of additional features: Reset the card before the last retry Read one sector at a time The legacy code spent much effort analyzing command errors, but commands fail fast, so it is simpler just to give all command errors the same number of retries.

2017-12-11mmc: block: Add CQE supportAdrian Hunter
Add CQE support to the block driver, including: - optionally using DCMD for flush requests - "manually" issuing discard requests - issuing read / write requests to the CQE - supporting block-layer timeouts - handling recovery - supporting re-tuning CQE offers 25% - 50% better random multi-threaded I/O. There is a slight (e.g. 2%) drop in sequential read speed but no observable change to sequential write. CQE automatically sends the commands to complete requests. However it only supports reads / writes and so-called "direct commands" (DCMD). Furthermore DCMD is limited to one command at a time, but discards require 3 commands. That makes issuing discards through CQE very awkward, but some CQE's don't support DCMD anyway. So for discards, the existing non-CQE approach is taken, where the mmc core code issues the 3 commands one at a time i.e. mmc_erase(). Where DCMD is used, is for issuing flushes.

2017-12-11mmc: block: Add blk-mq supportAdrian Hunter
Define and use a blk-mq queue. Discards and flushes are processed synchronously, but reads and writes asynchronously. In order to support slow DMA unmapping, DMA unmapping is not done until after the next request is started. That means the request is not completed until then.

2017-12-08kmemcheck: rip it out for realMichal Hocko
Commit 4675ff05de2d ("kmemcheck: rip it out") has removed the code but for some reason SPDX header stayed in place. This looks like a rebase mistake in the mmotm tree or the merge mistake. Let's drop those leftovers as well. Signed-off-by: Michal Hocko <mhocko@suse.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
