Merge branch 'for-4.19-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu 

Dennis writes:
  "percpu fixes for-4.19-rc8

   The new percpu allocator introduced in 4.14 had a missing free for
   the percpu metadata. This caused a memory leak when percpu memory is
   being churned resulting in the allocation and deallocation of percpu
   memory chunks"

* 'for-4.19-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/dennis/percpu:
  percpu: stop leaking bitmap metadata blocks
