From: Hans Holmberg <hans.holmberg@xxxxxxxxxxxx> This patch series fixes the(currently incomplete) write error handling in pblk by: * queuing and re-submitting failed writes in the write buffer * evacuating valid data data in lines with write failures, so the chunk(s) with write failures can be reset to a known state by the fw Lines with failures in smeta are put back on the free list. Failed chunks will be reset on the next use. If a write failes in emeta, the lba list is cached so the line can be garbage collected without scanning the out-of-band area.
