    Description

      Striping data obtained via getxattr() is not byte-swapped before returning it to the user. The attached C program demonstrates the problem and produces the following output on a PPC client.

      Expected stripe size 2097152, got 8192
Expected stripe count 3, got 768
Expected lmm magic 0bd10bd0, got d00bd10b

      I've taken a stab at a fix which I'll push to gerrit.
