2007-02-14[PATCH] sysctl: remove insert_at_head from register_sysctlEric W. Biederman
The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 7Arjan van de Ven

2007-02-08[NET]: user of the jiffies rounding code: NetworkingArjan van de Ven
This patch introduces users of the round_jiffies() function in the networking code. These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run.

2007-02-08[NETLINK]: Don't BUG on undersized allocationsPatrick McHardy
Currently netlink users BUG when the allocated skb for an event notification is undersized. While this is certainly a kernel bug, its not critical and crashing the kernel is too drastic, especially when considering that these errors have appeared multiple times in the past and it BUGs even if no listeners are present. This patch replaces BUG by WARN_ON and changes the notification functions to inform potential listeners of undersized allocations using a unique error code (EMSGSIZE).

2006-12-08[NETPOLL]: make arp replies through netpoll use mac address of senderNeil Horman
Back in 2.4 arp requests that were recevied by netpoll were processed in netconsole_receive_skb, where they were responded to using the src mac of the request sender. In the 2.6 kernel arp_reply is responsible for this function, but instead of using the src mac address of the incomming request, the stored mac address that was registered for the netconsole application is used. While this is usually ok, it can lead to failures in netpoll in some situations (specifically situations where a network may have two gateways, as arp requests from one may be responded to using the mac address of the other). This patch reverts the behavior to what we had in 2.4, in which all arp requests are sent back using the src address of the request sender.

2006-12-07[NET]: Memory barrier cleanupsRalf Baechle
I believe all the below memory barriers only matter on SMP so therefore the smp_* variant of the barrier should be used. I'm wondering if the barrier in net/ipv4/inet_timewait_sock.c should be dropped entirely. schedule_work's implementation currently implies a memory barrier and I think sane semantics of schedule_work() should imply a memory barrier, as needed so the caller shouldn't have to worry. It's not quite obvious why the barrier in net/packet/af_packet.c is needed; maybe it should be implied through flush_dcache_page?
