Hi Eric, After merging the userns tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: kernel/pid_namespace.c: In function 'create_pid_namespace': kernel/pid_namespace.c:105:7: error: too many arguments to function 'in_userns' if (!in_userns(parent_pid_ns->user_ns, user_ns)) ^ In file included from kernel/pid_namespace.c:13:0: include/linux/user_namespace.h:148:20: note: declared here static inline bool in_userns(const struct user_namespace *target_ns) ^ Caused by commit 1f1b28d80cd9 ("userns,pidns: Verify the userns for new pid namespaces") I have used the userns tree from next-20170719 for today. -- 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
