Enough small fixes have pilled up to make it worth a release: A Google patch adds sched_setaffinity, sched_getaffinity support. Openembedded uses kexec_load(). Gentoo folks add a Kbuild fix. ipconfig no longer wild guesses a nameserver when none is provided by the DHCP server. strndup() and unlinkat() saw fixes for various problems. codingstyle cleanup in kinit and tools. git repository: git://git.kernel.org/pub...

Hi, folks, We would like to run a container on a server, the reason being the COST of a Sybase license (it's by core), and what we can afford is a 4-core license. Now, the server's a nice Dell w/ 32 cores, so, ideally, what we want to do is set up containers, then, in one container, *only* have it see 4 cores, while the rest of the server, including (possibly) other containers, can see

change from v2: no code change, fix typos, update some comments change from v1: a simplier definition of default vcpu_is_preempted skip mahcine type check on ppc, and add config. remove dedicated macro. add one patch to drop overload of rwsem_spin_on_owner and mutex_spin_on_owner. add more comments thanks boqun and Peter's suggestion. This patch set aims to fix lock holder preemption
