Subject: [PATCH V2 1/4] block: define parsed_partitions.flags as 'unsigned char'
Date: Wed, 24 Feb 2021 11:58:27 +0800 [thread overview]
Message-ID: <20210224035830.990123-2-ming.lei@redhat.com> (raw)
In-Reply-To: <20210224035830.990123-1-ming.lei@redhat.com>
So far, only 3 partition flags are used, it is enough to hold it in
'unsigned char'.
