    Subject[KVM PATCH v2 0/2] irqfd enhancements
    Date
    (Applies to kvm.git/master:11b06403)

    The following patches are cleanups/enhancements for IRQFD now that
    we have lockless interrupt injection. For more details, please see
    the patch headers.

    These patches pass checkpatch, and are fully tested. Please consider
    for merging. They are an enhancement only, so there is no urgency
    to push to mainline until a suitable merge window presents itself.

    Kind Regards,
    -Greg

    [ Change log:

    v2:
    *) dropped original cleanup which relied on the user registering
    MSI based GSIs or we may crash at runtime. Instead, we now
    check at registration whether the GSI supports lockless
    operation and dynamically adapt to either the original
    deferred path for lock-based injections, or direct for lockless.

    v1:
    *) original release
    ]

    KVM: Directly inject interrupts if they support lockless operation
    KVM: export lockless GSI attribute
