[PATCH-possible bugfix] xfs: ensure extents are read as be64

From: Harvey Harrison
Date: Mon Apr 14 2008 - 23:28:59 EST


The debug code reads the extents in cpu-order rather than BE. Make the
debug code match.

Possibly 2.6.25 material....if it actually is a bug. See elsewhere
in the same file that reads as be64. (look for ep->l0).
