  lib/cpumask: update comment for cpumask_local_spread() (2022-12-15 14:44:43 -0800)

----------------------------------------------------------------
Hi Linus,

Please pull bitmap patches for v6.2. They spent in -next for more than
a week without any issues. The branch consists of:

- optimize small_const path for find_next_bit() and friends (me);

  Introduces small_const_nbits_off() and uses it in find_next_bit()-like
  functions to allow static optimization when all bits to search are
  withing a word boundary, even if not a 1st word.

- cpumask: improve on cpumask_local_spread() locality (me):

  The series makes cpumask_local_spread() picking Nth CPU based on NUMA
  hop distances, which is better than picking CPUs from a given node and
  if there's no N cpus - from a random node (how it works now).

- sched, net: NUMA-aware CPU spreading interface (Valentin Schneider,
  Tariq Toukan):

  Iterators for NUMA-aware CPUs traversing. Better alternative for
  cpumask_local_spread(), when it's needed to enumerate all CPUs.

Thanks,
Yury
