Subject: [PATCH] lightnvm: pblk fix for 4.13
Date: Thu, 27 Jul 2017 16:49:49 +0200	[thread overview]
Message-ID: <1501166990-24366-1-git-send-email-javier@javigon.com> (raw)

Hi Jens,

Can you pick up this fix for 4.13? It is a fix to a read corruption in
pblk that has been there form the beginning. It is due to a bad bio
manipulation in the case that an I/O containing lbas that are invalid,
point to data in the host cache and point to data on the device, all
three in a single bio.

The patch applies on top of you for-4.13/block and is available too at:
  - https://github.com/OpenChannelSSD/linux/tree/pblk.for-4.13

I marked the patch to fix the original pblk commit, but it does not
apply anymore on the original 4.12 code. How do we handle these
situations? We make a backport when Greg makes 4.12 stable?

Thanks,
Javier
