+# Bug 985074 - Verify stale inode/dentry mappings are cleaned out.
+#
+# This test verifies that an inode/dentry mapping for a file removed via a
+# separate mount point is cleaned up appropriately. We create a file and hard
+# link from client 1. Next we remove the link via client 2. Finally, from client
+# 1 we attempt to rename the original filename to the name of the just removed
+# hard link.
+#
+# If the inode is not unlinked properly, the removed directory entry can resolve
+# to an inode (on the client that never saw the rm) that ends up passed down
+# through the lookup call. If md-cache holds valid metadata on the inode (due to
+# a large timeout value or recent lookup on the valid name), it is tricked into
+# returning a successful lookup that should have returned ENOENT. This manifests
+# as an error from the mv command in the following test sequence because file
+# and file.link resolve to the same file:
+#
+# # mv /mnt/glusterfs/0/file /mnt/glusterfs/0/file.link
+# mv: `/mnt/glusterfs/0/file' and `/mnt/glusterfs/0/file.link' are the same file
