I would not say "no" to a fix for this issue:

I'm not sure this URL actually points to a relevant issue ?
Once that is in place, I would be happy to put this back into -next.
At some point, we will need to get rid of the concept of wildcard hazard
pointers, as those end up instead emulating RCU, but I don't see that
as an immediate obstacle.
I already have the implementation which eliminates the wildcard if we
care about this. It was part of a previous hazptr series version.
Do you want me to resurrect it on top of the current series ?
This depends on:
- ptr_eq(),
- then use ptr_eq() to compare the loaded pointer (pre mb)
with the re-loaded pointer (post-mb).
