• fd5e1b5db   sched: Remove unneeded __ref tag ... Browse Code »

  Those two functions no longer call alloc_bootmmem_cpumask_var(),
  so no need to tag them with __init_refok.

  Lets not use the bootmem allocator in cpupri_init() as slab is already up when
  it is run.

• eaa958402   cpumask: alloc zeroed cpumask for static cpumask_var_ts ... Browse Code »

  These are defined as static cpumask_var_t so if MAXSMP is not used,
  they are cleared already. Avoid surprises when MAXSMP is enabled.

• 13b8bd0a5   sched_rt: don't allocate cpumask in fastpath ... Browse Code »

  Impact: cleanup

  As pointed out by Steven Rostedt. Since the arg in question is
  unused, we simply change cpupri_find() to accept NULL.

  init_rootdomain() calls alloc_bootmem_cpumask_var() at system boot,
  so does cpupri_init().

• 68e74568f   sched: convert struct cpupri_vec cpumask_var_t. ... Browse Code »

  Impact: stack usage reduction, (future) size reduction for large NR_CPUS.

  Dynamically allocating cpumasks (when CONFIG_CPUMASK_OFFSTACK) saves
  space for small nr_cpu_ids but big CONFIG_NR_CPUS.

  The fact cpupro_init is called both before and after the slab is
  available makes for an ugly parameter unfortunately.

  We also use cpumask_any_and to get rid of a temporary in cpupri_find.

• 6e0534f27   sched: use a 2-d bitmap for searching lowest-pri CPU ... Browse Code »

  The current code use a linear algorithm which causes scaling issues
  on larger SMP machines. This patch replaces that algorithm with a
  2-dimensional bitmap to reduce latencies in the wake-up path.
