From cbd430cc95386a8937796d6d5ff7a07b72222f11 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.
