Re: [PATCH net-next] mm: page_frag: fix a compile error when kernel is not compiled

page_frag test module is an out of tree module, but built using KDIR as the main kernel tree, the mm test suite is just getting skipped if newly added page_frag test module fails to compile due to kernel not yet compiled.

Fix the above problem by ensuring both kernel is built first and a newer kernel which has page_frag_cache.h is used.

Tested-by: Mark Brown broonie@kernel.org

(for the case where we skip the build.)
