Should this include a Fixes tag? The commit addresses a bug introduced
in commit 13ee5d67a7c9 ("bpf: Support stack arguments for bpf functions").
Additionally, bot+bpf-ci@kernel.org noted in v5 review on lore that this
commit fixes a bug but lacks the tag:

Suggested: Fixes: 13ee5d67a7c9 ("bpf: Support stack arguments for bpf functions")
