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
