*	[media] v4l2: vb2-dma-sg: fix potential security hole	Andrzej Pietrasiewicz	2011-03-22	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \|	Memory allocated by alloc_page() function might contain some potentially important data from other system processes. The patch adds a flag to zero the allocated page before giving it to videobuf2 (and then to userspace).

\| \| \| \| \| \| \| \| \| \| \|	This patch fixes two minor memory leaks in videobuf2-dma-sg module. They might happen only in case some other operations (like memory allocation) failed.

*	[media] v4l: videobuf2: add DMA scatter/gather allocator	Andrzej Pietrasiewicz	2011-03-21	1	-0/+292
	Add an implementation of DMA scatter/gather allocator and handling routines for videobuf2. For mmap operation mode it is implemented on top of alloc_page + sg_set_page/_free_page. For userptr operation mode it is implemented on top of get_user_pages + sg_set_page/put_page.
