  "message": "media: v4l2-core: push taking ioctl mutex down to ioctl handler\n\nThe ioctl serialization mutex (vdev-\u003elock or q-\u003elock for vb2 queues)\nwas taken at the highest level in v4l2-dev.c. This prevents more\nfine-grained locking since at that level we cannot examine the ioctl\narguments, we can only do that after video_usercopy is called.\n\nSo push the locking down to __video_do_ioctl() and subdev_do_ioctl_lock().\n\nThis also allows us to make a few functions in v4l2-ioctl.c static and\nvideo_usercopy() is no longer exported.\n\nThe locking scheme is not changed by this patch, just pushed down.\n\nSigned-off-by: Hans Verkuil \u003chansverk@cisco.com\u003e\nSigned-off-by: Mauro Carvalho Chehab \u003cmchehab+samsung@kernel.org\u003e\n",
