Hi Greg, After merging the driver-core tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/block/zram/zram_drv.c:1296:28: error: expected ')' before numeric constant static CLASS_ATTR(hot_add, 0400, hot_add_show, NULL); ^ drivers/block/zram/zram_drv.c:1330:3: error: 'class_attr_hot_add' undeclared here (not in a function) &class_attr_hot_add.attr, ^ drivers/block/zram/zram_drv.c:1282:16: warning: 'hot_add_show' defined but not used [-Wunused-function] static ssize_t hot_add_show(struct class *class, ^ Caused by commit 27104a53d02e ("zram: use class_groups instead of class_attrs") I have reverted that commit for today (and commit ecbaa83ee84c ("driver core: remove class_attrs from struct class") temporarily so the the tree will build). -- Cheers, Stephen Rothwell -- 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
