Subject: [PATCH 4.9 05/31] btrfs: define SUPER_FLAG_METADUMP_V2
Date: Tue, 12 Jun 2018 18:46:08 +0200 [thread overview]
Message-ID: <20180612164621.006764182@linuxfoundation.org> (raw)
In-Reply-To: <20180612164620.797338191@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Anand Jain <Anand.Jain@oracle.com>
commit e2731e55884f2138a252b0a3d7b24d57e49c3c59 upstream.
btrfs-progs uses super flag bit BTRFS_SUPER_FLAG_METADUMP_V2 (1ULL << 34).
So just define that in kernel so that we know its been used.
