2012-07-30[media] cx25821: Remove useless struct i2c_algo_bit_dataEzequiel García2-5/+0
The field 'struct i2c_algo_bit_data i2c_algo' is wrongly confused with struct i2c_algorithm. Moreover, i2c_algo field is not used since i2c is registered using i2c_add_adpater() and not i2c_bit_add_bus(). Therefore, it's safe to remove it. Tested by compilation only.

2012-07-30[media] V4L: Add capability flags for memory-to-memory devicesSylwester Nawrocki10-16/+70
This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE capability flags that are intended to be used for memory-to-memory (M2M) devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT. V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT capability flags are left untouched and will be removed in future, after a transition period required for existing applications to be adapted to check only for V4L2_CAP_VIDEO_M2M.

commit c6cffba4ffa2 (ipv4: Fix input route performance regression.) added various fatal races with dst refcounts. crashes happen on tcp workloads if routes are added/deleted at the same time. The dst_free() calls from free_fib_info_rcu() are clearly racy. We need instead regular dst refcounting (dst_release()) and make sure dst_release() is aware of RCU grace periods : Add DST_RCU_FREE flag so that dst_release() respects an RCU grace period before dst destruction for cached dst Introduce a new inet_sk_rx_dst_set() helper, using atomic_inc_not_zero() to make sure we dont increase a zero refcount (On a dst currently waiting an rcu grace period before destruction) rt_cache_route() must take a reference on the new cached route, and release it if was not able to install it.
