From: Sage Weil Date: Thu, 18 Nov 2010 17:15:07 +0000 (-0800) Subject: ceph: fix readdir EOVERFLOW on 32-bit archs X-Git-Tag: upstream/snapshot3+hdmi~12407^2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3105c19c450ac7c18ab28c19d364b588767261b3;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git 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.
