Subject: [PATCH 2/5] f2fs: support norecovery mount option
Date: Tue, 27 Jan 2015 15:31:40 -0800	[thread overview]
Message-ID: <1422401503-4769-2-git-send-email-jaegeuk@kernel.org> (raw)
In-Reply-To: <1422401503-4769-1-git-send-email-jaegeuk@kernel.org>

This patch adds a mount option, norecovery, which is mostly same as
disable_roll_forward. The only difference is that norecovery should be activated
with read-only mount option.

This can be used when user wants to check whether f2fs is mountable or not
without any recovery process. (e.g., xfstests/200)
