Hi everybody, Here are 5 patches to the uvcvideo driver that implements proper locking where it was missing and switch from ioctl to unlocked_ioctl, getting rid of the BKL.
As locking can be tricky, patch review would be appreciated. Laurent Pinchart (5): uvcvideo: Lock controls mutex when querying menus uvcvideo: Move mutex lock/unlock inside uvc_free_buffers uvcvideo: Move mmap() handler to uvc_queue.c uvcvideo: Lock stream mutex when accessing format-related information uvcvideo: Convert to unlocked_ioctl drivers/media/video/uvc/uvc_ctrl.c | 48 +++++++++- drivers/media/video/uvc/uvc_queue.c | 133 +++++++++++++++++++++----- drivers/media/video/uvc/uvc_v4l2.c | 183 +++++++++++------------------------ drivers/media/video/uvc/uvc_video.c | 3 - drivers/media/video/uvc/uvcvideo.h | 10 ++- 5 files changed, 221 insertions(+), 156 deletions(-) -- Regards, Laurent Pinchart -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
