Subject: [PATCH] vhost: make CONFIG_VHOST depend on CONFIG_EVENTFD
Date: Tue, 31 Mar 2020 10:29:02 +0800 [thread overview]
Message-ID: <20200331022902.12229-1-jasowang@redhat.com> (raw)
After commit ec9d8449a99b ("vhost: refine vhost and vringh kconfig"),
CONFIG_VHOST could be enabled independently. This means we need make
CONFIG_VHOST depend on CONFIG_EVENTFD, otherwise we break compiling
without CONFIG_EVENTFD.
Reported-by: Randy Dunlap <rdunlap@infradead.org>
Fixes: ec9d8449a99b ("vhost: refine vhost and vringh kconfig")
