From 43e6c111824c75940a586cd7d3fe6a5ff1d5104f Mon Sep 17 00:00:00 2001 From: Mikulas Patocka Date: Wed, 24 Aug 2022 07:25:57 -0400 Subject: [PATCH] dm: change from DMWARN to DMERR or DMCRIT for fatal errors Change DMWARN to DMERR in cases when there is an unrecoverable error. Change DMWARN to DMCRIT when handling of a case is unimplemented.
