[PATCH] vhost: drop vringh dependency

Show all headers | View raw

vringh isn't used by vhost net or scsi - it's used
by CAIF only at the moment. Drop the dependency.

Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Including vhost directory twice isn't pretty - we just want it
scanned if either of the symbols is defined.
Something along the lines of

obj-$(subst %m%,m,$(subst %y%,y,$(CONFIG_VHOST)(CONFIG_VHOST_RING))) += vhost/

would also work, but seems uglier.
