Thanks for the respin - this one does apply, and 3/3 now falls through into free_aisb: the way mainline does, so both of my objections to v1 are addressed. One thing left in 1/3: the conflict resolution keeps 6.12's existing in-loop cur_pages = atomic_long_read(&user->locked_vm); in account_mem() as well as adding the pre-loop read. It is harmless, but it is the only line where 6.12 would then differ from mainline and from 6.18/7.1. Could you drop the in-loop read and resend? The same artifact is in the 6.6 and 6.1 submissions. While you are respinning: 0cfe660559e8 ("KVM: s390: pci: Fix aisb calculation") is missing from 6.18, 6.12, 6.6 and 6.1 - only 7.1 has it. kvm_zpci_set_airq() on these trees still computes the AISB address as aift->sbv->vector + (zdev->aisb / 64) * 8, which goes out of bounds past 64 forwarded devices. Could you or Matthew include it in the resend? -- Thanks, Sasha
