From 15289dc85b2d03d42d7e479476254be2b17c65d5 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Mon, 3 Mar 2014 09:20:44 +0800 Subject: [PATCH] ceph: let MDS adjust readdir 'frag' If readdir 'frag' is adjusted, readdir 'offset' should be reset. Otherwise some dentries may be lost when readdir and fragmenting directory happen at the some. Another way to fix this issue is let MDS adjust readdir 'frag'. The code that handles MDS reply reset the readdir 'offset' if the readdir reply is different than the requested one.
