Subject: [PATCH 1/5] f2fs: change default compression algorithm
Date: Tue, 10 Mar 2020 20:50:05 +0800	[thread overview]
Message-ID: <20200310125009.12966-1-yuchao0@huawei.com> (raw)

Use LZ4 as default compression algorithm, as compared to LZO, it shows
almost the same compression ratio and much better decompression speed.
