mm: page_frag: fix a compile error when kernel is not compiledpage_frag test module is an out of tree module, but builtusing KDIR as the main kernel tree, the mm test suite isjust getting skipped if newly added page_frag test modulefails to compile due to kernel not yet compiled.Fix the above problem by ensuring both kernel is built firstand a newer kernel which has page_frag_cache.h is used.CC: Andrew Morton CC: Alexander Duyck CC: Linux-MM Fixes: 7fef0dec415c ("mm: page_frag: add a test module for page_frag")Fixes: 65941f10caf2 ("mm: move the page fragment allocator from page_alloc into its own file")Reported-by: Mark Brown Signed-off-by: Yunsheng Lin Tested-by: Mark Brown Link: https://patch.msgid.link/20241119033012.257525-1-linyunsheng@huawei.comSigned-off-by: Paolo Abeni List of files: /linux-6.15/tools/testing/selftests/mm/page_frag/Makefile

mm: page_frag: add a test module for page_fragThe testing is done by ensuring that the fragment allocatedfrom a frag_frag_cache instance is pushed into a ptr_ringinstance in a kthread binded to a specified cpu, and a kthreadbinded to a specified cpu will pop the fragment from theptr_ring and free the fragment.CC: Andrew Morton CC: Linux-MM Signed-off-by: Yunsheng Lin Reviewed-by: Alexander Duyck Link: https://patch.msgid.link/20241028115343.3405838-2-linyunsheng@huawei.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/tools/testing/selftests/mm/page_frag/Makefile
