Hi Jason,
we use this lock to protect the eventfd_ctx and irq from race
conditions,
We don't support irq notification from vDPA device driver in this
version, do we still have race condition?
as we discussed before:
(1)if vendor change IRQ after DRIVER_OK, through they should not do this, but they can.
(2)if user space changes ctx.
Thanks
Yes, but then everything happens in context of syscall (ioctl), so vq
mutex is sufficient I guess?
Thanks
