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? Changes since V1: - Make advanced_bio a bool to improve readability, as suggested by Jens Thanks, Javier Javier González (1): lightnvm: pblk: advance bio according to lba index drivers/lightnvm/pblk-rb.c | 4 ++-- rivers/lightnvm/pblk-read.c | 23 ++++++++++++++++------- drivers/lightnvm/pblk.h | 2 +- 3 files changed, 19 insertions(+), 10 deletions(-) -- 2.7.4
