I think moving the line tsleep(sc, PRIBIO, "mdwait", 0); to just after the following `if' statement may do the trick. If the wakeup() from mddestroy() comes in before md_kthread() gets to the main loop, then it would be missed. I think jhb posted a better way of synchronising with kthreads during their destruction, but I haven't found the time to look into that yet.
