      Clean up x86 unsafe_get/put_user() type handling · 334a023e
      Linus Torvalds authored
      Al noticed that unsafe_put_user() had type problems, and fixed them in
      commit a7cc722f
      
       ("fix unsafe_put_user()"), which made me look more
      at those functions.
      
      It turns out that unsafe_get_user() had a type issue too: it limited the
      largest size of the type it could handle to "unsigned long".  Which is
      fine with the current users, but doesn't match our existing normal
      get_user() semantics, which can also handle "u64" even when that does
      not fit in a long.
      
      While at it, also clean up the type cast in unsafe_put_user().  We
      actually want to just make it an assignment to the expected type of the
      pointer, because we actually do want warnings from types that don't
      convert silently.  And it makes the code more readable by not having
      that one very long and complex line.
      
      [ This patch might become stable material if we ever end up back-porting
        any new users of the unsafe uaccess code, but as things stand now this
        doesn't matter for any current existing uses. ]

      __put_user_size() relies upon its first argument having the same type as what
      the second one points to; the only other user makes sure of that and
      unsafe_put_user() should do the same.

      nvme-fc: stop queues on error detection · 2952a879
      James Smart authored
      Per the recommendation by Sagi on:
      http://lists.infradead.org/pipermail/linux-nvme/2017-April/009261.html
      
      
      
      Rather than waiting for reset work thread to stop queues and abort the ios,
      immediately stop the queues on error detection. Reset thread will restop
      the queues (as it's called on other paths), but it does not appear to have
      a side effect.
