Subject: [PATCH] ubifs: default to zstd compression
Date: Mon,  5 Apr 2021 16:29:35 +0100	[thread overview]
Message-ID: <20210405152935.148129-1-rsalvaterra@gmail.com> (raw)

Compared to lzo and zlib, zstd is the best all-around performer, both in terms
of speed and compression ratio. Set it as the default, if available.
