From d9ffc4f77073e7e1ca731f21804769de9c094b87 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Tue, 18 Mar 2014 10:15:29 +0800 Subject: [PATCH] ceph: set mds_wanted when MDS reply changes a cap to auth cap When adjusting caps client wants, MDS does not record caps that are not allowed. For non-auth MDS, it does not record WR caps. So when a MDS reply changes a non-auth cap to auth cap, client needs to set cap's mds_wanted according to the reply.
