Subject: [PATCH] virtiofsd: Fix check of chown()'s return value
Date: Fri, 07 May 2021 18:12:28 +0200 [thread overview]
Message-ID: <162040394890.714971.15502455176528384778.stgit@bahia.lan> (raw)
Otherwise you always get this warning when using --socket-group=users
vhost socket failed to set group to users (100)
While here, print out the error if chown() fails.
