Subject: [PATCH 00/18] lightnvm: pblk patches for 4.14

Hi Jens,

Here is the pblk patchset for this window.

The most notable patches are on the read path:
  - ("lightnvm: pblk: check lba sanity on read path") uses the lba
    stored on the out-of-bound area to verify that the read ppa
    corresponds to the lba pointed to by the read bio.
  - ("lightnvm: pblk: guarantee line integrity on reads") guarantees
    that if a line is being GC'ed and a read comes in the middle, that
    line is not being moved into the free list until the read completes.
    Otherwise, the line could be reclaimed to be erased and re-written,
    thus causing data corruption.

The rest of the patches are are basically bug fixes and refactoring to
improve code readability.

The patches apply on your for-4.14/block, and you can be found at:

Thanks,
Javier
