Subject: [PATCH v2 02/10] update linux headers
Date: Mon, 17 Jan 2022 20:43:23 +0800	[thread overview]
Message-ID: <20220117124331.1642-3-longpeng2@huawei.com> (raw)
In-Reply-To: <20220117124331.1642-1-longpeng2@huawei.com>

From: Longpeng <longpeng2@huawei.com>

Update linux headers to 5.xxx(kernel part is not merged yet)

To support generic vdpa deivce, we need add the following ioctls:
- VHOST_VDPA_GET_CONFIG_SIZE: get the configuration size.
- VHOST_VDPA_GET_VQS_NUM: get the count of supported virtqueues.
