  dm flakey: introduce "error_writes" feature (2016-12-13 15:01:31 -0500)

Please pull, thanks.
Mike

----------------------------------------------------------------
. various fixes and improvements to request-based DM and DM multipath

. some locking improvements in DM bufio

. add Kconfig option to disable the DM block manager's extra locking
  which mainly serves as a developer tool

. a few bug fixes to DM's persistent-data

. a couple changes to prepare for multipage biovec support in the block
  layer

. various improvements and cleanups in the DM core, DM cache, DM raid
  and DM crypt

. add ability to have DM crypt use keys from the kernel key retention
  service

. add a new "error_writes" feature to the DM flakey target, reads are
  left unchanged in this mode
