Subject: [RFC PATCH 11/12] btrfs-progs: replace: disable in HMZONED device
Date: Fri, 10 Aug 2018 03:11:04 +0900	[thread overview]
Message-ID: <20180809181105.12856-11-naota@elisp.net> (raw)
In-Reply-To: <20180809181105.12856-1-naota@elisp.net>

As show in the kernel patches, device replace feature needs more works to
complete. Disable the feature for now.
