Subject: [PATCH v2] f2fs: allow compression of files without blocks
Date: Thu, 7 Jul 2022 17:09:24 +0800 [thread overview]
Message-ID: <20220707090924.4183376-1-chaoliu719@gmail.com> (raw)
From: Chao Liu <liuchao@coolpad.com>
Files created by truncate(1) have a size but no blocks, so
they can be allowed to enable compression.
