From mboxrd@z Thu Jan 1 00:00:00 1970 From: jean-philippe.brucker@arm.com (Jean-Philippe Brucker) Date: Fri, 11 May 2018 20:06:12 +0100 Subject: [PATCH v2 11/40] mm: export symbol find_get_task_by_vpid In-Reply-To: <20180511190641.23008-1-jean-philippe.brucker@arm.com> References: <20180511190641.23008-1-jean-philippe.brucker@arm.com> Message-ID: <20180511190641.23008-12-jean-philippe.brucker@arm.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Userspace drivers implemented with VFIO might want to bind sub-processes to their devices. In a VFIO ioctl, they provide a pid that is used to find a task and its mm. Since VFIO can be built as a module, export the find_get_task_by_vpid symbol.
