Subject: [RFC PATCH 1/4] btrfs: turn checksum type define into a union
Date: Thu, 25 Jul 2019 11:33:48 +0200 [thread overview]
Message-ID: <6601e14425550304e1ba8b5317e74a5f806d6a34.1564046812.git.jthumshirn@suse.de> (raw)

In-Reply-To: <cover.1564046812.git.jthumshirn@suse.de>
Turn the checksum type definition into a union. This eases later addition
of new checksums.
