Replace with globally

2016-12-24T19:46:01Z

This was entirely automated, using the script by Al: PATT='^[[:blank:]]*#[[:blank:]]*include[[:blank:]]*' sed -i -e "s!$PATT!#include !" \ $(git grep -l "$PATT"|grep -v ^include/linux/uaccess.h) to do the replacement at the end of the merge window.

[media] media: dvb_ringbuffer: Add memory barriers

2016-07-09T10:57:47Z

Implement memory barriers according to Documentation/circular-buffers.txt: - use smp_store_release() to update ringbuffer read/write pointers - use smp_load_acquire() to load write pointer on reader side - use ACCESS_ONCE() to load read pointer on writer side This fixes data stream corruptions observed e.g. on an ARM Cortex-A9 quad core system with different types (PCI, USB) of DVB tuners.

[media] ngene: properly handle __user ptr

2014-09-08T13:00:52Z

Sparse is complaining about ngene's bad usage of a __user ptr: >> drivers/media/pci/ngene/ngene-dvb.c:62:48: sparse: incorrect type in argument 2 (different address spaces) drivers/media/pci/ngene/ngene-dvb.c:62:48: expected unsigned char const [usertype] *buf drivers/media/pci/ngene/ngene-dvb.c:62:48: got char const [noderef] *buf As this is intercepting a .write() file ops, we can't just memcpy. We need to use copy_from_user. Reported-by: kbuild test robot Signed-off-by: Mauro Carvalho Chehab

[media] dvb: move the dvb core one level up

2012-08-14T02:08:14Z

just like the V4L2 core, move the DVB core to drivers/media, as the intention is to get rid of both "video" and "dvb" directories. Signed-off-by: Mauro Carvalho Chehab
