From d165a7a6f5aa05dfdfc164e24c11b6458a523ff7 Mon Sep 17 00:00:00 2001 From: Igor Konopko Date: Sat, 4 May 2019 20:38:02 +0200 Subject: [PATCH] lightnvm: pblk: propagate errors when reading meta MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Read errors are not correctly propagated. Errors are cleared before returning control to the io submitter. Change the behaviour such that all read errors exept high ecc read warning status is returned appropriately.
