relay_subbufs_consumed — update the buffer's sub-buffers-consumed count


void relay_subbufs_consumed (struct rchan * chan,
 unsigned int cpu,
 size_t subbufs_consumed);


struct rchan * chan

the channel

unsigned int cpu

the cpu associated with the channel buffer to update

size_t subbufs_consumed

number of sub-buffers to add to current buf's count


Adds to the channel buffer's consumed sub-buffer count. subbufs_consumed should be the number of sub-buffers newly consumed, not the total consumed.

NOTE. Kernel clients don't need to call this function if the channel mode is 'overwrite'.
