From: John L. Hammond <john.hamm...@intel.com> By the time that a struct lmv_user_md reaches lmv_placement_policy() it has already been converted to little endian. Therefore use the appropriate macros around accesses to this this field. This issue was found by rewriting the definition of struct lmv_user_md to use the __leXX typedefs and running sparse.
