From 659d1a39458fdc2b73ad2d3512d1ea2ce6f7566d Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Sun, 6 Jan 2013 09:15:55 +0800 Subject: [PATCH] mds: properly set error_dentry for discover reply If MDCache::handle_discover() receives an 'discover path' request but can not find the base inode. It should properly set the 'error_dentry' to make sure MDCache::handle_discover_reply() checks correct object's wait queue.
