Subject: [PATCH 2/5] f2fs: force compressed data into warm area
Date: Tue, 10 Mar 2020 20:50:06 +0800	[thread overview]
Message-ID: <20200310125009.12966-2-yuchao0@huawei.com> (raw)
In-Reply-To: <20200310125009.12966-1-yuchao0@huawei.com>

Generally, data shows better continuity in warm data area as its
default allocation direction is right, in order to enhance
sequential read/write performance of compress inode, let's force
compress data into warm area.
