  scst_mem: Fix a memory leak triggered by the scst_user driver
  
  Avoid that the following memory leak can occur:
  - sgv_pool_alloc() is called with SGV_POOL_RETURN_OBJ_ON_ALLOC_FAIL
    set, with neither SGV_POOL_NO_ALLOC_ON_CACHE_MISS nor
    SGV_POOL_ALLOC_NO_CACHED set and with 'size' such that
    sgv_max_local_pages < pages_to_alloc <= pool->max_cached_pages.
  - sgv_get_obj() and sgv_alloc_arrays() succeed.
  - sgv_alloc_sg_entries() fails.
  - sgv_get_obj() returns the SGV object with no buffers.
  - A call to sgv_pool_free() adds this object to the recycle list.
  - sgv_pool_alloc() is called a second time with the same parameters.
  - sgv_get_obj() retrieves the object that was previously added to
    the recycle list.
  - sgv_alloc_arrays() is called and overwrites the obj->sg_entries
    pointer although it still points at allocated memory, resulting
    in a memory leak.

  scst_local: Change max_lun into SCST_MAX_LUN (16383)
  
  Today SCST does not support LUN numbers >= 16384. Additionally,
  there is a bug in older Linux initiator systems that prevents
  proper handling of LUN numbers >= 2**32. See also Hannes Reinecke,
  scsi_scan: Fixup scsilun_to_int(), June 25, 2014 (commit ID
  d9e5d6183715e691b37afd3785c311d05cd1338d). Hence set max_lun to
  16383.

  vdisk_blockio: Make large COMPARE AND WRITE requests work for stacked block devices
      
  Stacked block devices impose weird restrictions on S/G-lists. Hence
  make the COMPARE AND WRITE implementation independent of these
  restrictions.
      
  Additionally, reduce the MAXIMUM COMPARE AND WRITE LENGTH limit from
  0xff (no limit) to 0xfe to reduce the maximum amount of memory allocated
  during a COMPARE AND WRITE. Also serialize COMPARE AND WRITE
  operations, fix the offset reported for miscompares and fix the start
  offset of the region that is synchronized if the FUA bit has been set.
