Subject: [PATCH v6 01/24] erofs: add on-disk layout
Date: Fri, 2 Aug 2019 20:53:24 +0800 [thread overview]
Message-ID: <20190802125347.166018-2-gaoxiang25@huawei.com> (raw)
In-Reply-To: <20190802125347.166018-1-gaoxiang25@huawei.com>
This commit adds the on-disk layout header file of erofs.
On-disk format is compatible with erofs-staging added in 4.19.
In addition, add EROFS_SUPER_MAGIC_V1 to magic.h.
