[GIT PULL 00/20] lightnvm updates for 4.18

[Matias BjÃrling]

Hi Jens,

Please pick up the following patches.

 - Hans reworked the write error recovery path in pblk.
 - Igor added extra error handling for lines, and fixed a bug in the
   pblk ringbuffer during GC.
 - Javier refactored the pblk code a bit, added extra error
   handling, and added checks to verify that data returned from drive
   is appropriate.
 - Marcin added some extra logic to manage the write buffer. Now
   MW_CUNITS can be zero and the size of write buffer can be changed
   at module load time.

Thanks,
Matias
