cpuset: fix the problem that cpuset_mem_spread_node() returns an offline node

2010-04-01T23:01:50+00:00

commit 5ab116c9349ef52d6fbd2e2917a53f13194b048e upstream. cpuset_mem_spread_node() returns an offline node, and causes an oops. This patch fixes it by initializing task->mems_allowed to node_states[N_HIGH_MEMORY], and updating task->mems_allowed when doing memory hotplug.

ima: initialize ima before inodes can be allocated

2010-02-07T08:06:22+00:00

ima wants to create an inode information struct (iint) when inodes are allocated. This means that at least the part of ima which does this allocation (the allocation is filled with information later) should before any inodes are created. To accomplish this we split the ima initialization routine placing the kmem cache allocator inside a security_initcall() function. Since this makes use of radix trees we also need to make sure that is initialized before security_initcall(). Signed-off-by: Eric Paris Acked-by: Mimi Zohar Signed-off-by: Al Viro

sched: Mark boot-cpu active before smp_init()

2009-12-16T18:01:53+00:00

A UP machine has 1 active cpu, not having the boot-cpu in the active map when starting the scheduler confuses things. Signed-off-by: Peter Zijlstra Cc: Mike Galbraith LKML-Reference: <20091216170517.423469527@chello.nl> Signed-off-by: Ingo Molnar

init/main.c: fix symbol shadows noise

2009-12-15T16:53:26+00:00

The symbol 'call' is a static symbol used for initcall_debug. This same symbol name is used locally by a couple functions and produces the following sparse warnings: warning: symbol 'call' shadows an earlier one Fix this noise by renaming the local symbols.

Jon confirms that recent modprobe will look in /proc/cmdline, so these cmdline options can still be used. See http://bugzilla.kernel.org/show_bug.cgi?id=14164 Reported-by: Adam Williamson Cc: stable@kernel.org Signed-off-by: Rusty Russell Signed-off-by: Linus Torvalds

* remove asm/atomic.h inclusion from linux/utsname.h -- not needed after kref conversion * remove linux/utsname.h inclusion from files which do not need it NOTE: it looks like fs/binfmt_elf.c do not need utsname.h, however due to some personality stuff it _is_ needed -- cowardly leave ELF-related headers and files alone.

rcu: Clean up code based on review feedback from Josh Triplett, part 2

2009-09-23T17:46:29+00:00

These issues identified during an old-fashioned face-to-face code review extending over many hours. o Add comments for tricky parts of code, and correct comments that have passed their sell-by date. o Get rid of the vestiges of rcu_init_sched(), which is no longer needed now that PREEMPT_RCU is gone. o Move the #include of rcutree_plugin.h to the end of rcutree.c, which means that, rather than having a random collection of forward declarations, the new set of forward declarations document the set of plugins. The new home for this #include also allows __rcu_init_preempt() to move into rcutree_plugin.h. o Fix rcu_preempt_check_callbacks() to be static. Suggested-by: Josh Triplett Signed-off-by: Paul E.
