Subject: [PATCH 0/1] btrfs-progs: fi usage: implement raid56
Date: Sun, 17 Mar 2019 13:51:49 +0100	[thread overview]
Message-ID: <20190317125150.26265-1-stephane_btrfs@lesimple.fr> (raw)

From: Stéphane Lesimple <stephane_btrfs@lesimple.fr>

For several years now, we've been missing RAID56
code in the `filesystem usage' btrfs subcommand.

This is my try at implementing it. I don't have
any production array using raid5 or raid6 yet, but
I've tried different combinations of devloop test
filesystems with different number of devices with
different sizes. And the reported informations
always seem correct.

Comments are obviously welcome.
