Hi Jesper,

I love your patch! Perhaps something to improve:

[auto build test WARNING on net-next/master]
[also build test WARNING on v5.4-rc6 next-20191108]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see]

base: 92da362c07d413786ab59db1665376fb63805586
        # apt-get install sparse
        # sparse version: v0.6.1-21-gb31adac-dirty
        make ARCH=x86_64 allmodconfig
        make C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__'

If you fix the issue, kindly add following tag
Reported-by: kbuild test robot <>

sparse warnings: (new ones prefixed by >>)

>> net/core/page_pool.c:379:6: sparse: sparse: symbol 'page_pool_empty_alloc_cache_once' was not declared. Should it be static?

Please review and possibly fold the followup patch.
