Subject: [uml-devel] [PATCH 12/16] UML - Remove useless sys_mount wrapper
Date: Mon, 07 Mar 2005 15:38:45 -0500 [thread overview]
Message-ID: <200503072038.j27Kcjbc003998@ccure.user-mode-linux.org> (raw)
um_mount did nothing but turn around and call sys_mount with the same
arguments. This makes it useless code, and it has been duly removed.
