Great, then can someone submit these in a format we can apply them in?
or do clean cherry-picks work properly?

Does this work:
Please backport upstream commit:
617e0491abe4 f2fs: sysfs: export linear_lookup in features directory
... to all stable branches up to and including linux-5.15.y.
If there are conflicts, I can do the backport myself and submit as patches.
