[GIT PULL] Block fixes for 4.15-rc

[GIT PULL] Block fixes for 4.15-rc

[Jens Axboe]

Hi Linus,

A selection of fixes/changes that should make it into this series. This
pull request contains:

- NVMe, two merges, containing:
	- pci-e, rdma, and fc fixes
	- Device quirks

- Fix for a badblocks leak in null_blk

- Pull bcache fixes from Michael Lyle. Most important is a regression
  fix for a case where bcache could return the wrong data in some
  circumstances.

- Regression fix for blktrace for a bug introduced in this series.

- blktrace cleanup for cgroup id.

- bdi registration error handling.

- Small series with cleanups for blk-wbt.

- Various little fixes for typos and the like.

Nothing earth shattering, most important are the NVMe and bcache fixes.

Please pull!

Hi Linus & Jens--

Just one small clarification:

The fix for the block-layer data corruption issue from NVMe multipath
work was already accepted in the previous pull.  The main fix in this
series is Rui Hua's fix for  a race condition regression where -EINTR
was returned to upper layers that didn't expect it.

Thanks,

Mike

Ah yes, thanks for the clarification, I mixed those two up.

[GIT PULL] Block fixes for 4.15-rc

[Jens Axboe]

Hi Linus,

It's been a few weeks, so here's a small collection of fixes that
should go into the current series.

This pull request contains:

- NVMe pull request from Christoph, with a few important fixes.

- kyber hang fix from Omar.

- A blk-throttl fix from Shaohua, fixing a case where we double charge
  a bio.

- Two call_single_data alignment fixes from me, fixing up some unfortunate
  changes that went into 4.14 without being properly reviewed on the
  block side (since nobody was CC'ed on the patch...).

- A bounce buffer fix in two parts, one from me and one from Ming.

- Revert bdi debug error handling patch. It's causing boot issues for some
  folks, and a week down the line, we're still no closer to a fix. Revert
  this patch for now until it's figured out, then we can retry for 4.16.

Please pull!
