From e1e44602021358336fb524affe53ce3c09b34beb Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 24 Jul 2019 07:59:51 -0400 Subject: ceph: allow copy_file_range when src and dst inode are same There is no reason to prevent this. The OSD should be able to handle this as long as the objects are different, and the existing code falls back when the offset into the object is different.
