There are no significant changes from v13, right? It would be helpful to mention this in the cover letter. It would also be helpful to describe how this was tested at least in the cover letter, but maybe in one of the commit messages too. For example I and two other people have tested the Qualcomm ICE support on top of this with https://lkml.kernel.org/linux-scsi/20200501045111.665881-1-ebiggers@kernel.org/. (BTW, I'll be rebasing, re-testing, and re-sending those patches soon.) Mediatek has also tested this with https://lkml.kernel.org/linux-scsi/20200304022101.14165-1-stanley.chu@mediatek.com/. - Eric
