But that is not in any tree that is included in linux-next (and when it
does appear, it will be in the tip tree which gets merged well after
the bpf-next tree).  I will include that patch as a merge fix up for
the bpf-next tree until that patch has gone into Linus' tree ... so,
someone has to ensure that this patch get into Linus tree *before* the
bpf-next tree.

So, do you see the problem?  Linus' tree is fine on its own.  The
bpf-next tree has a patch that breaks Linus' tree, but the breakage is
not seen in the bpf-next tree because it is base on v5.14 and the
interacting patch is in v5.15-rc1.
