Hi all, After merging the vfs-brauner tree, today's linux-next build (arm64 kselftest) failed like this: CC statmount_test_ns statmount_test_ns.c:37:19: error: static declaration of 'wait_for_pid' follows non-static declaration 37 | static inline int wait_for_pid(pid_t pid) | ^~~~~~~~~~~~ In file included from statmount_test_ns.c:17: ../utils.h:47:12: note: previous declaration of 'wait_for_pid' with type 'int(pid_t)' {aka 'int(int)'} 47 | extern int wait_for_pid(pid_t pid); | ^~~~~~~~~~~~ make[1]: *** [../../lib.mk:225: /tmp/next/arm6 Caused by commit 32f54f2bbccfd (selftests/filesystems: add tests for empty mount namespaces) I have used the version from next-20260312 instead.
