From 3105c19c450ac7c18ab28c19d364b588767261b3 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 18 Nov 2010 09:15:07 -0800 Subject: ceph: fix readdir EOVERFLOW on 32-bit archs One of the readdir filldir_t callers was passing the raw ceph 64-bit ino instead of the hashed 32-bit one, producing an EOVERFLOW in the filler callback. Fix this by calling the ceph_vino_to_ino() helper to do the conversion.
