Damn it, I couldn't remember how to add not-for-commit comments to a patch.
I RTFMed and thought that was what "git mailinfo --scissors" wanted.

(Normally, I put it down with the diffstat, but preferred a more
prominent place for this conversation.)

It worked without, but yeah... since I can't figure *how* it works.

Well, I did a quick eyeball-scan, then did my usual build, then
an allyesconfig and an allmodconfig.

I found some other alarming things, but nothing related to this.

E.g.
drivers/net/ethernet/intel/i40e/i40e_debugfs.c: In function 'i40e_dbg_dump_desc':
drivers/net/ethernet/intel/i40e/i40e_debugfs.c:855:1: warning: the frame size of 8192 bytes is larger than 2048 bytes [-Wframe-larger-than=]
 }

(Honestly, I didn't wait for the allmodconfig to finish, since I
expected it to fail within the first few hundred modules if it was going to
fail at all, but it has finished now.)
