From 5f8badbcbeac298a77ee634a10a375f3e66923f9 Mon Sep 17 00:00:00 2001 From: Amit Date: Thu, 12 Sep 2019 08:29:39 +0300 Subject: [PATCH] nvmet: fix a wrong error status returned in error log page When the command data_len cannot hold all the controller errors, we should simply return as much errors as we can fit instead of failing the command.
