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"

percpu: stop leaking bitmap metadata blocks
