Subject: [PATCH] ioctl_userfaultfd.2: update uffdio_api.features description
Date: Wed, 28 Jun 2017 15:30:03 +0300	[thread overview]
Message-ID: <1498653003-25227-1-git-send-email-rppt@linux.vnet.ibm.com> (raw)

There is no requirement that uffdio_api.features must be zero for newer
kernels. This field actually defines what features user space would like to
enable.
