Subject: [PATCH 0/3] lightnvm: pblk: support variable OOB size

This patchset adds pblk support for variable metadata sizes on the out
of bound area.

Igor, Marcin, you sent a patch some time ago implementing a similar
functionality, but it never got re-posted after review. Can you test
this and see if it works for your case? I did not implement support for
outlined metadata for the case where the reported OOB area is 0. It
should be pretty simple to do that on top of these patches though.

Thanks,
Javier
