Subject: [PATCH v6 15/17] powerpc/vas: Define window open ioctls API
Date: Tue, 8 Aug 2017 16:07:00 -0700 [thread overview]
Message-ID: <1502233622-9330-16-git-send-email-sukadev@linux.vnet.ibm.com> (raw)
In-Reply-To: <1502233622-9330-1-git-send-email-sukadev@linux.vnet.ibm.com>
Define the VAS_TX_WIN_OPEN and VAS_RX_WIN_OPEN ioctl interface. Each user
of VAS, like the NX-FTW driver in a follow-on patch, should implement
these ioctls.
