Subject: [PATCH V3 11/13] vfio: Use select for eventfd
Date: Sun, 22 Aug 2021 17:36:00 +0300 [thread overview]
Message-ID: <20210822143602.153816-12-yishaih@nvidia.com> (raw)
In-Reply-To: <20210822143602.153816-1-yishaih@nvidia.com>
From: Jason Gunthorpe <jgg@nvidia.com>
If VFIO_VIRQFD is required then turn on eventfd automatically.
The majority of kconfig users of the EVENTFD use select not depends on.
