[PATCH v1] s390/extmem: remove stale -ENOSPC comment and handling

From: David Hildenbrand
Date: Tue Jun 30 2020 - 04:42:53 EST


segment_load() will no longer return -ENOSPC. If a segment overlaps with
storage, we now also return -EBUSY. Remove the stale comment from
__segment_load() and the stale handling from segment_warning().
