Alex Elder b82d167be6 rbd: prevent open for image being removed ... An open request for a mapped rbd image can arrive while removal of that mapping is underway. We need to prevent such an open request from succeeding. (It appears that Maciej Galkiewicz ran into this problem.) Define and use a "removing" flag to indicate a mapping is getting removed. Set it in the remove path after verifying nothing holds the device open. And check it in the open path before allowing the open to proceed. Acquire the rbd device's lock around each of these spots to avoid any races accessing the flags and open_count fields.
