From ca4ddaac7fa710a250bbd650cc719425bec973a0 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Thu, 26 Aug 2021 13:39:10 +0300 Subject: vfio: Use select for eventfd If VFIO_VIRQFD is required then turn on eventfd automatically. The majority of kconfig users of the EVENTFD use select not depends on.

The next patch increases the nesting level a lot so this is a nice preparatory simplification.
