init: allow mounting arbitrary non-blockdevice filesystems as root
Currently the only non-blockdevice filesystems that can be used as the
initial root filesystem are NFS and CIFS, which use the magic
"root=/dev/nfs" and "root=/dev/cifs" syntax that requires the root
device file system details to come from filesystem specific kernel
command line options.
Add a little bit of new code that allows to just pass arbitrary
string mount options to any non-blockdevice filesystems so that it can
be mounted as the root file system.
For example a virtiofs root file system can be mounted using the
following syntax:
"root=myfs rootfstype=virtiofs rw"
Based on an earlier patch from Vivek Goyal <vgoyal@redhat.com>.
