From d38954ed1b76a2814057cd4af92c6966bceb3d3c Mon Sep 17 00:00:00 2001 From: Igor Konopko Date: Sat, 4 May 2019 20:37:54 +0200 Subject: lightnvm: pblk: set proper read status in bio MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently in case of read errors, bi_status is not set properly which leads to returning inproper data to layers above. This patch fix that by setting proper status in case of read errors. Also remove unnecessary warn_once(), which does not make sense in that place, since user bio is not used for interation with drive and thus bi_status will not be set here.
