From 4e1ec35ef4f7bbf70c3e08e7c246946551f19e93 Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Thu, 16 Jun 2011 07:48:22 +0000 Subject: core: fill 'ia_ino' from 'ia_gfid' in 'storage/posix' to preserve same ino number take the least significant 64bit from gfid and assign it to 'ia_ino', hence for a given file (or directory), the 'ia_ino' number is always same, and we need not worry about the 'itransform' in 'cluster/*' translators.
