The PCI core is not changing the values, just writing them twice while active. The patch addresses the general case of any change to an active window, but not atomically.

Treat a crypto API error indication as a verification failure.

The n_reject counter counts how many times ICP rejects an irq because of priority in real mode. The redelivery of an lsi that is still asserted after eoi doesn't fall into this category, so the increasement there is removed.
