cpumask: alloc zeroed cpumask for static cpumask_var_ts

2009-06-09T13:00:27Z

These are defined as static cpumask_var_t so if MAXSMP is not used, they are cleared already. Avoid surprises when MAXSMP is enabled. Signed-off-by: Yinghai Lu Signed-off-by: Rusty Russell

sched_rt: don't allocate cpumask in fastpath

2009-04-01T11:24:51Z

Impact: cleanup As pointed out by Steven Rostedt. Since the arg in question is unused, we simply change cpupri_find() to accept NULL. Reported-by: Steven Rostedt Signed-off-by: Rusty Russell LKML-Reference: <200903251501.22664.rusty@rustcorp.com.au> Signed-off-by: Ingo Molnar

sched_rt: don't use first_cpu on cpumask created with cpumask_and

2009-02-01T09:49:52Z

cpumask_and() only initializes nr_cpu_ids bits, so the (deprecated) first_cpu() might find one of those uninitialized bits if nr_cpu_ids is less than NR_CPUS (as it can be for CONFIG_CPUMASK_OFFSTACK). Signed-off-by: Rusty Russell Signed-off-by: Ingo Molnar

sched: fix build error in kernel/sched_rt.c when RT_GROUP_SCHED && !SMP

2009-01-14T14:10:04Z

Ingo found a build error in the scheduler when RT_GROUP_SCHED was enabled, but SMP was not. This patch rearranges the code such that it is a little more streamlined and compiles under all permutations of SMP, UP and RT_GROUP_SCHED. It was boot tested on my 4-way x86_64 and it still passes preempt-test. Signed-off-by: Gregory Haskins

Impact: reduce stack usage, cleanup Use a cpumask_var_t in find_lowest_rq() and clean up other old cpumask_t calls. Signed-off-by: Mike Travis
