Subject: [PATCH v2 1/7] erofs: on-disk format should have explicitly assigned numbers
Date: Fri, 30 Aug 2019 11:00:34 +0800
Message-ID: <20190830030040.10599-1-gaoxiang25@huawei.com> (raw)

As Christoph claimed [1], on-disk format should have
explicitly assigned numbers. I have to change it.

[1] https://lore.kernel.org/r/20190829095954.GB20598@infradead.org/
Reported-by: Christoph Hellwig <hch@infradead.org>
Signed-off-by: Gao Xiang <gaoxiang25@huawei.com>
---
v2: no change, just resend in case of dependency problem;

I have to say one word "all patches are trivial".
