Patch 4 is absolutely critical and without which 1-3 don't really matter
all that much. It also needs to be backported (I will be doing some manual
backports for that once landed).
Patches 5-8 could be held back to 6.13 if preferred as, while nice to have
as they do further work to eliminate this class of bugs, are not as
important.
