Merge tag 'sysctl-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull sysctl updates from Luis Chamberlain:
 "Just some boring cleanups on the sysctl front for this release"

* tag 'sysctl-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux:
  kernel/sysctl-test: use SYSCTL_{ZERO/ONE_HUNDRED} instead of i_{zero/one_hundred}
  kernel/sysctl.c: move sysctl_vals and sysctl_long_vals to sysctl.c
  sysctl: remove max_extfrag_threshold
  kernel/sysctl.c: remove unnecessary (void*) conversions
  proc: remove initialization assignment
