From 0685235ffd9dbdb9ccbda587f8a3c83ad1d5a921 Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Mon, 19 Nov 2012 10:49:07 +0800 Subject: ceph: Don't add dirty inode to dirty list if caps is in migration Add dirty inode to cap_dirty_migrating list instead, this can avoid ceph_flush_dirty_caps() entering infinite loop.
