From cbf55001b2ddb814329735641be5d29b08c82b08 Mon Sep 17 00:00:00 2001 From: Eliezer Tamir Date: Mon, 8 Jul 2013 16:20:34 +0300 Subject: net: rename low latency sockets functions to busy poll Rename functions in include/net/ll_poll.h to busy wait. Clarify documentation about expected power use increase. Rename POLL_LL to POLL_BUSY_LOOP. Add need_resched() testing to poll/select busy loops. Note, that in select and poll can_busy_poll is dynamic and is updated continuously to reflect the existence of supported sockets with valid queue information.
