From ed7e9ad0908a8c2a502f49ceed940d0ce122fe8b Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 30 May 2018 16:11:52 -0400 Subject: NFSv4: Fix sillyrename to return the delegation when appropriate Ensure that we pass down the inode of the file being deleted so that we can return any delegation being held.
