Subject: [PATCH v4 6/7] mv: use flags mode for update_mode
Date: Thu, 23 Jun 2022 19:41:19 +0800 [thread overview]
Message-ID: <20220623114120.12768-7-shaoxuan.yuan02@gmail.com> (raw)
In-Reply-To: <20220623114120.12768-1-shaoxuan.yuan02@gmail.com>
As suggested by Derrick [1],
move the in-line definition of "enum update_mode" to the top
of the file and make it use "flags" mode (each state is a different
bit in the word).
Change the flag assignments from '=' (single assignment) to '|='
(additive). Also change flag evaluation from '==' to '&', etc.
