      [BKL] add 'might_sleep()' to the outermost lock taker · f01eb364
      Linus Torvalds authored
      As shown by the previous patch (6698e347: "tty: Fix BKL taken under a
      spinlock bug introduced in the BKL split") the BKL removal is prone to
      some subtle issues, where removing the BKL in one place may in fact make
      a previously nested BKL call the new outer call, and then prone to nasty
      deadlocks with other spinlocks.
      
      In general, we should never take the BKL while we're holding a spinlock,
      so let's just add a "might_sleep()" to it (even though the BKL doesn't
      technically sleep - at least not yet), and we'll get nice warnings the
      next time this kind of problem happens during BKL removal.
