Pull Ceph fix from Sage Weil:
 "This fixes a problem preventing the kernel and userland librbd
  libraries from sharing data with the new format 2 images"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  rbd: use the correct length for format 2 object names

Format 2 objects use 16 characters for the object name suffix to be
able to express the full 64-bit range of object numbers. Format 1
images only use 12 characters for this. Using 12-character names for
format 2 caused userspace and kernel rbd clients to read differently
named objects, which made an image written by one client look empty to
the other client.

Pull block layer fixes from Jens Axboe:
 "Outside of bcache (which really isn't super big), these are all
  few-liners.  There are a few important fixes in here:

   - Fix blk pm sleeping when holding the queue lock

   - A small collection of bcache fixes that have been done and tested
     since bcache was included in this merge window.

   - A fix for a raid5 regression introduced with the bio changes.

   - Two important fixes for mtip32xx, fixing an oops and potential data
     corruption (or hang) due to wrong bio iteration on stacked devices."

If a new logical drive is added and the CCISS_REGNEWD ioctl is invoked
(as is normal with the Array Configuration Utility) the process will
hang as below.  It attempts to acquire the same mutex twice, once in
do_ioctl() and once in cciss_unlocked_open().  The BKL was recursive,
the mutex isn't.

This mutex usage was added into the ioctl path when the big kernel lock
was removed.  As it turns out, these paths are all thread safe anyway
(or can easily be made so) and we don't want ioctl() to be single
threaded in any case.

  NVMe: Add MSI support

  Return the result from user admin command IOCTL even in case of failure
  NVMe: Do not cancel command multiple times

  MAINTAINERS: update NVM EXPRESS DRIVER file list
  NVMe: Fix a signedness bug in nvme_trans_modesel_get_mp
  NVMe: Remove redundant version.h header include

Some devices only have support for MSI, not MSI-X.  While MSI is more
limited, it still provides better performance than line-based interrupts.

to receive one pktcdvd fix. It fixes a highly theoretical issue with using.
pktcdvd to work with media that'd be larger than 2TB :) But it's a correct.
fix and makes static checkers shut up about improperly cleaning upper.
32bits.

Static checkers complain about widening the binary "not" operations here
because sectors are u64 and "(pd)->settings.size" is unsigned int.
It unintentionally clears the high 32 bits of the sector.  This means
that the driver won't work for devices with over 2TB of space.  Since
this is a DVD drive, we're unlikely to reach that limit, but we may as
well silence the warning.
