Subject: [PATCH] Add BTRFS Filesystem Metadata Image
|
|
|
|
|
Patch-mainline: Submitted to file@mx.gw.com, 20 Oct 2016
|
|
|
|
|
|
|
|
|
|
The btrfs-image in its uncompressed form contains a directly usable
|
|
|
|
|
superblock. Rather than duplicate the superblock printer, split
|
|
|
|
|
that out and use it with both the on-disk superblock and the ones
|
|
|
|
|
contained within the image.
