I pushed the patch to for-5.18-fixes and will send a PR to Linus tomorrow.
The for-5.19 and for-next branches always are in sync and currently based
on 5.18-rc1. I will rebase them on rc2 next week to have the name revert
in and avoid conflicts.

Use 5.19 + the name revert patch for your work. That will correspond to
for-5.19 next week.
