[PATCH v2 net-next 0/3] net: low latency sockets follow ups

From: Eliezer Tamir
Date: Wed Jun 12 2013 - 07:20:12 EST


Here are two clean up patches, plus one that adds a socket option for LLS.

Patch 1 removes the config menu for NET_LL_RX_POLL and defaults to y.
Patch 2 converts sysctl_net_ll_poll into an unsigned int
Patch 3 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.


Change log:

- 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.
