Subject: [PATCH] mm, meminit: Recalculate pcpu batch and high limits after init completes -fix
Date: Wed, 23 Oct 2019 09:47:05 +0100 [thread overview]
Message-ID: <20191023084705.GD3016@techsingularity.net> (raw)
LKP reported the following build problem from two hunks that did not
survive the reshuffling of the series reordering.
ld: mm/page_alloc.o: in function `page_alloc_init_late':
mm/page_alloc.c:1956: undefined reference to `zone_pcp_update'
This is a fix for the mmotm patch
mm-meminit-recalculate-pcpu-batch-and-high-limits-after-init-completes.patch
Reported-by: kbuild test robot <lkp@intel.com>
