Regarding the release blockers email, and the qualification of this
series:
- a regression introduced since 4.12
This is not a regression, since AFAICT the posted interrupt code has
always been like this.
- a severe bug of a 4.13 feature
The bug seems to impact people using PCI-passthrough on Intel hardware
that supports posted interrupts (aka APICv). In my opinion, we either
fix it or disable APICv by default (now it's currently enabled by
default).
Thanks, Roger.
