Patch 1 fixes a possible deadlock in subflow_error_report() reported by
lockdep. The report was in fact a false positive but the modification
makes sense and silences lockdep to allow syzkaller to find real issues.
The regression has been introduced in v5.12.

Patch 2 is a refactoring needed to be able to fix the two next issues.
It improves the situation and can be backported up to v6.0.

Patches 3 and 4 fix UaF reported by KASAN. It fixes issues potentially
visible since v5.7 and v5.19 but only reproducible until recently
(v6.0). These two patches depend on patch 2/7.

Patch 5 fixes the order of the printed values: expected vs seen values.
The regression has been introduced recently: present in Linus' tree but
not in a tagged version yet.

Patch 6 adds missing ro_after_init flags. A previous patch added them
for other functions but these two have been missed. This previous patch
has been backported to stable versions (up to v5.12) so probably better
to do the same here.

Patch 7 fixes tcp_set_state() being called twice in a row since v5.10.

I'm sorry to ask for that but is it possible not to apply these patches?

Done, thanks!
