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
