| Subject: mm: hide a #warning for COMPILE_TEST |
| |
| From: Arnd Bergmann <arnd@arndb.de> |
| |
| commit af27d9403f5b80685b79c88425086edccecaf711 upstream. |
| |
| We get a warning about some slow configurations in randconfig kernels: |
| |
| mm/memory.c:83:2: error: #warning Unfortunate NUMA and NUMA Balancing config, growing page-frame for last_cpupid. [-Werror=cpp] |
| |
| The warning is reasonable by itself, but gets in the way of randconfig |
| build testing, so I'm hiding it whenever CONFIG_COMPILE_TEST is set. |
| |
| The warning was added in 2013 in commit 75980e97dacc ("mm: fold |
| page->_last_nid into page->flags where possible"). |
