Subject: [PATCH] jbd2: use shrink_type type instead of bool type for __jbd2_journal_clean_checkpoint_list()
Date: Mon, 1 Apr 2024 09:16:14 +0800 [thread overview]
Message-ID: <20240401011614.3650958-1-yebin10@huawei.com> (raw)
"enum shrink_type" can clearly express the meaning of the parameter of
__jbd2_journal_clean_checkpoint_list(), and there is no need to use the
bool type.
