Revision c15e0ae42c8e5a61e9aca8aac920517cf7b3e94e authored by Li RongQing on 09 March 2022, 08:35:44 UTC, committed by Paolo Bonzini on 02 April 2022, 09:37:27 UTC
If apic_id is less than min, and (max - apic_id) is greater than
KVM_IPI_CLUSTER_SIZE, then the third check condition is satisfied but
the new apic_id does not fit the bitmask. In this case __send_ipi_mask
should send the IPI.
This is mostly theoretical, but it can happen if the apic_ids on three
iterations of the loop are for example 1, KVM_IPI_CLUSTER_SIZE, 0.
