Will this not still have the problem with defconfigs? They don't set
VHOST_MENU ...
Looks not, since it was enabled by default.
I tested this on s390/ppc defconfigs:
# make ARCH=s390 defconfig
*** Default configuration is based on 'defconfig'
#
# No change to .config
#
# grep CONFIG_VHOST .config
CONFIG_VHOST_IOTLB=m
CONFIG_VHOST=m
CONFIG_VHOST_MENU=y
CONFIG_VHOST_NET=m
CONFIG_VHOST_VSOCK=m
# CONFIG_VHOST_VDPA is not set
# CONFIG_VHOST_CROSS_ENDIAN_LEGACY is not set
Thanks
