Hi Andrew, After merging the akpm-current tree, today's linux-next build (powerpc allnoconfig) failed like this: mm/built-in.o: In function `shrink_slab.part.73.constprop.83': vmscan.c:(.text+0xf760): undefined reference to `__srcu_read_lock' vmscan.c:(.text+0xf924): undefined reference to `__srcu_read_unlock' mm/built-in.o: In function `unregister_shrinker': (.text+0xfa60): undefined reference to `synchronize_srcu' mm/built-in.o:(.data+0x1e8): undefined reference to `process_srcu' Caused by commit dab937da82f9 ("mm: srcu-ify shrinkers") I have reverted that commit for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
