2008-01-25Preempt-RCU: update RCU Documentation.Paul E. McKenney

2008-01-25cpu-hotplug: replace lock_cpu_hotplug() with get_online_cpus()Gautham R Shenoy
Replace all lock_cpu_hotplug/unlock_cpu_hotplug from the kernel and use get_online_cpus and put_online_cpus instead as it highlights the refcount semantics in these operations. The new API guarantees protection against the cpu-hotplug operation, but it doesn't guarantee serialized access to any of the local data structures. Hence the changes needs to be reviewed. In case of pseries_add_processor/pseries_remove_processor, use cpu_maps_update_begin()/cpu_maps_update_done() as we're modifying the cpu_present_map there.

2008-01-08[IPV4] ipconfig: Fix regression in ip command line processingAmos Waterland
The recent changes for ip command line processing fixed some problems but unfortunately broke some common usage scenarios. In current 2.6.24-rc6 the following command line results in no IP address assignment, which is surely a regression: ip=10.0.2.15::10.0.2.2:255.255.255.0::eth0:off Please find below a patch that works for all cases I can find.

2007-12-26[IPV4]: Fix ip command line processing.Simon Horman
Recently the documentation in Documentation/nfsroot.txt was update to note that in fact ip=off and ip=::::::off as the latter is ignored and the default (on) is used. This was certainly a step in the direction of reducing confusion. But it seems to me that the code ought to be fixed up so that ip=::::::off actually turns off ip autoconfiguration. This patch also notes more specifically that ip=on (aka ip=::::::on) is the default. Signed-off-by: Simon Horman <horms@verge.net.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-12-07bonding: Add new layer2+3 hash for xor/802.3ad modesJay Vosburgh
Add new hash for balance-xor and 802.3ad modes. Originally submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by Jay Vosburgh to move setting of hash policy out of line, tweak the documentation update and add version update to 3.2.2. Glenn's original comment follows: Included is a patch for a new xmit_hash_policy for the bonding driver that selects slaves based on MAC and IP information. This is a middle ground between what currently exists in the layer2 only policy and the layer3+4 policy. This policy strives to be fully 802.3ad compliant by transmitting every packet of any particular flow over the same link. As documented the layer3+4 policy is not fully compliant for extreme cases such as ip fragmentation, so this policy is a nice compromise for environments that require full compliance but desire more than the layer2 only policy.

2007-11-29The namespaces compatibility list docPavel Emelyanov
People discuss how the namespaces are working/going-to-work together. Ted Ts'o proposed to create some document that describes what problems user may have when he/she creates some new namespace, but keeps others shared. I liked this idea, so here's the initial version of such a document with the problems I currently have in mind and can describe somewhat audibly - the "namespaces compatibility list". The Documentation/namespaces/ directory is about to contain more docs about the namespaces stuff.

On some machine, this bug causes bad names to appear in /proc, such as /proc/sys/dev/parport/parport0/devices/T^/�X^/�, on others, the plip proc node is completely missing.
