Subject: [PATCH 17/22] staging: erofs: remove clusterbits in sbi
Date: Mon, 29 Jul 2019 14:51:54 +0800
Message-ID: <20190729065159.62378-18-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20190729065159.62378-1-gaoxiang25@huawei.com>

clustersize can now be set on per-file basis
rather than per-filesystem basis.
