Patch 1 converts sysctl_net_ll_poll into an unsigned int Patch 2 converts low latency sockets to sched_clock. Patch 3 removes the config menu for NET_LL_RX_POLL and defaults to y. Patch 4 adds an SO_LL socket option to allow per-socket control of busy polling. I will reply to this thread with a patch to sockperf that enables the socket option. (unchanged from v2) Again, thanks to everyone for their comments. -Eliezer Change log: v4 - Fixed possible overflow, pointed out by Eric Dumazet. (reordered the patches) v3 - Suggested by David Miller and Stephen Hemminger: added a patch to covert from get_cycles() to sched_clock(), remove dependency on X86_TSC. - Suggested by Eric Dumazet: un-exported sysctl_net_ll_poll since for now it's not needed in modules. v2 - added a patch to convert sysctl_net_ll_poll into an unsigned int. - suggested by Eric Dimazet: treat sk_ll_usec as a u_int rather than a u_long. - suggested by Ben Huchings: allow unprivileged user to decrease SO_LL value, correct return value when operation is not allowed. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
