FL_FILE_PVT locks are no longer tied to a particular pid, and are instead inheritable by child processes. Report a l_pid of '-1' for these sorts of locks since the pid is somewhat meaningless for them. This precedent comes from FreeBSD. There, POSIX and flock() locks can conflict with one another. If fcntl(F_GETLK, ...) returns a lock set with flock() then the l_pid member cannot be a process ID because the lock is not held by a process as such. Acked-by: J.
