Hi Theodore, After merging the ext4 tree, today's linux-next build (x86_64 allmodconfig) failed like this: ERROR: "wbc_account_io" [fs/ext4/ext4.ko] undefined! ERROR: "bio_associate_blkcg" [fs/ext4/ext4.ko] undefined! Caused by commit 001e4a8775f6 ("ext4: implement cgroup writeback support") I have used the ext4 tree from next-20150722 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
