(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
