Yeah, my fault, I still "manually" read that, and my script properly spit out: Commit id aad885e774966e97b675dfe928da164214a71605 queued in: queue-6.19/kvm-x86-mmu-drop-zap-existing-present-spte-even-when-creating-an-mmio-spte.patch queued in: queue-6.18/kvm-x86-mmu-drop-zap-existing-present-spte-even-when-creating-an-mmio-spte.patch queued in: queue-6.12/kvm-x86-mmu-drop-zap-existing-present-spte-even-when-creating-an-mmio-spte.patch queued in: queue-6.6/kvm-x86-mmu-drop-zap-existing-present-spte-even-when-creating-an-mmio-spte.patch fixed in: 5.13 > ○ 6.19 ○ 6.18 ○ 6.12 ○ 6.6 ○ 6.1 ○ 5.15 ○ 5.10 But I guess I seleced "5.10" accidentally as well. Sorry about that, my fault, one of these days I'll make the script a bit smarter to "pre-populate" the checkboxes with what it thinks should be happening here, and not require me to actually read values :) thanks, greg k-h
