Javier González a4809fee4e lightnvm: pblk: check lba sanity on read path ... As part of pblk's recovery scheme, we store the lba mapped to each physical sector on the device's out-of-bound (OOB) area. On the read path, we can use this information to validate that the data being delivered to the upper layers corresponds to the lba being requested. The cost of this check is an extra copy on the DMA region on the device and an extra comparison in the host, given that (i) the OOB area is being read together with the data in the media, and (ii) the DMA region allocated for the ppa list can be reused for the metadata stored on the OOB area.
