From 797a937e5dd8db0092add633a80f3cd698e182df Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 6 Feb 2015 13:03:12 -0500 Subject: Btrfs-progs: Introduce metadump_v2 The METADUMP super flag makes us skip doing the chunk tree reading which isn't helpful for the new restore since we have a valid chunk tree. But we still want to have a way for the kernel to know that this is a metadump restore so it doesn't do things like verify data checksums. We also want to skip some of the device extent checks in fsck since those will obviously not match.
