      Restore direct_io / truncate locking API · 37fbf4bf
      Anton Altaparmakov authored
      With kernel 3.1, Christoph removed i_alloc_sem and replaced it with
      calls (namely inode_dio_wait() and inode_dio_done()) which are
      EXPORT_SYMBOL_GPL() thus they cannot be used by non-GPL file systems and
      further inode_dio_wait() was pushed from notify_change() into the file
      system ->setattr() method but no non-GPL file system can make this call.
      
      That means non-GPL file systems cannot exist any more unless they do not
      use any VFS functionality related to reading/writing as far as I can
      tell or at least as long as they want to implement direct i/o.
      
      Both Linus and Al (and others) have said on LKML that this breakage of
      the VFS API should not have happened and that the change was simply
      missed as it was not documented in the change logs of the patches that
      did those changes.
      
      This patch changes the two function exports in question to be
      EXPORT_SYMBOL() thus restoring the VFS API as it used to be - accessible
      for all modules.
      
      Christoph, who introduced the two functions and exported them GPL-only
      is CC-ed on this patch to give him the opportunity to object to the
      symbols being changed in this manner if he did indeed intend them to be
      GPL-only and does not want them to become available to all modules.

      A fix from Jesper Juhl removes an assignment in an ASSERT when a compare
      is intended.  Two fixes from Mitsuo Hayasaka address off-by-ones in XFS
      quota enforcement.

        something that isn't strictly speaking a regression but some upstream
        changes causes it to show in lockdep now while it didn't before, and
        finally a trivial one for rusty to make his life easier later on
        removing the old cpumask cruft. '

      xhci: Fix encoding for HS bulk/control NAK rate. · 340a3504
      Sarah Sharp authored
      The xHCI 0.96 spec says that HS bulk and control endpoint NAK rate must
      be encoded as an exponent of two number of microframes.  The endpoint
      descriptor has the NAK rate encoded in number of microframes.  We were
      just copying the value from the endpoint descriptor into the endpoint
      context interval field, which was not correct.  This lead to the VIA
      host rejecting the add of a bulk OUT endpoint from any USB 2.0 mass
      storage device.
      
      The fix is to use the correct encoding.  Refactor the code to convert
      number of frames to an exponential number of microframes, and make sure
      we convert the number of microframes in HS bulk and control endpoints to
      an exponent.
      
      This should be back ported to kernels as old as 2.6.31, that contain the
      commit dfa49c4a "USB: xhci - fix math
      in xhci_get_endpoint_interval"
