Subject: [PATCH] btrfs-progs: fsck: Add more explanation on low memory mode
Date: Fri, 20 May 2016 10:21:07 +0800	[thread overview]
Message-ID: <1463710867-27127-1-git-send-email-quwenruo@cn.fujitsu.com> (raw)

It seems the initial support for low memory mode will come in recent
release, it's better to add more explanation on the unsupported
functions, to avoid user reporting known bugs.
