From 648fa60fa7de3ca6f6303e1721591ad73def9cf0 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 22 Jun 2023 17:06:44 +0200 Subject: block: don't return -EINVAL for not found names in devt_from_devname When we didn't find a device and didn't guess it might be a partition, it might still show up later, so don't disable rootwait for it by returning -EINVAL.
