    net/9p: Switch to wait_event_killable() · 9523feac

    Because userspace gets Very Unhappy when calls like stat() and execve()
    return -EINTR on 9p filesystem mounts. For instance, when bash is
    looking in PATH for things to execute and some SIGCHLD interrupts
    stat(), bash can throw a spurious 'command not found' since it doesn't
    retry the stat().
    
    In practice, hitting the problem is rare and needs a really
    slow/bogged down 9p server.
