      [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.

      The fasync path takes the BKL (it probably doesn't need to in fact)
      while holding the file_list spinlock.  You can't do that with the kernel
      lock: it causes lock inversions and deadlocks.
      
      Leave the BKL over that bit for the moment.
