I guess it is just a typo for you as you have correctly added other Fixes tag. If you end up re-spinning, please correct this Also, just to understand, "A Fixes: tag indicates that the patch fixes an issue in a previous commit. It is used to make it easy to determine where a bug originated, which can help review a bug fix" from https://docs.kernel.org/process/submitting-patches.html should there not be just single Fixes tag? as bug originated from one commit, may be the commit that actually broke the functionality. P.S. Not expert on this, just trying to learn. Kamlesh

It should be at least 12 hex digits i.e. more is fine. It is possible that some commits need more than 12 hex digits of the SHA1 to be uniquely identified in some git repositories already. I guess checkpatch needs a patch. > Also, just to understand, > > "A Fixes: tag indicates that the patch fixes an issue in a previous > commit.

While we generally prefer that a patch only fix one bug, it is very possible that the bug may have been introduced in more than one commit e.g. in different files.
