Subject: [PATCH 3/6] f2fs: do f2fs_balance_fs when block is allocated
Date: Mon, 25 Jan 2016 14:05:28 -0800	[thread overview]
Message-ID: <1453759531-16076-3-git-send-email-jaegeuk@kernel.org> (raw)
In-Reply-To: <1453759531-16076-1-git-send-email-jaegeuk@kernel.org>

We should consider data block allocation to trigger f2fs_balance_fs.
