I will submit a new version without the link. The above warning is not for the link. After wrapping the line, however, checkpatch does warn the link line like below. WARNING: Prefer a maximum 75 chars per line (possible unwrapped commit description?) #13: [1]: https://lore.kernel.org/damon/66131775-180b-4b9f-b7ce-61a3e077b6e6@huawei-partners.com/T/#m278d3c9bbedcceaf2efa51e3dc7b40a40654e51c But, it should be ok to just ignore the warning for the link line. So, please wrap the line, but keep the link. Thanks, SJ [...]
