Al Viro 7ffdea7ea3 locking in fs/9p ->readdir() ... ... is really excessive. First of all, ->readdir() is serialized by file->f_path.dentry->d_inode->i_mutex; playing with file->f_path.dentry->d_lock is not buying you anything. Moreover, rdir->mutex is pointless for exactly the same reason - you'll never see contention on it. While we are at it, there's no point in having rdir->buf a pointer - you have it point just past the end of rdir, so it might as well be a flex array (and no, it's not a gccism).
