From 333bd9b59c4298a7cb7796f3bd4ee444376c68c6 Mon Sep 17 00:00:00 2001 From: Amar Tumballi Date: Thu, 20 Oct 2011 12:20:34 +0530 Subject: storage/posix: fill 'ia_ino' from 'ia_gfid' 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.
