Hi Mauro, This single patch fixes setting the write parameter to 1 for get_user_pages() on writable buffers. Without this using USERPTR buffers with the dma-contig mem type will corrupt system memory. This is directly applicable to fixes and master branches and should be pulled into both. The following changes since commit 4bad5d2d25099a42e146d7b18d2b98950ed287f5: [media] dvb_net: Convert local hex dump to print_hex_dump_debug (2015-02-03 18:24:44 -0200) are available in the git repository at: ssh://linuxtv.org/git/sailus/media_tree.git vb2-fix for you to fetch changes up to 5a433fbc3ead7d65143bf039eb77512d0558e2e7: vb2: Fix dma_dir setting for dma-contig mem type (2015-02-13 12:14:31 +0200) ---------------------------------------------------------------- Sakari Ailus (1): vb2: Fix dma_dir setting for dma-contig mem type drivers/media/v4l2-core/videobuf2-dma-contig.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) -- Kind regards, Sakari Ailus e-mail: sakari.ailus@xxxxxx XMPP: sailus@xxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
