Hi Jilei,
Please notice the patch format requirement, the subject of the patch should start with "vdpa/ifc: ".
You also need to keep it concise, around ~50 characters.
Refer " doc/guides/contributing/patches.rst" for more detail.
Back to this patch, it looks we can just change function ifcvf_dma_map(struct ifcvf_internal *internal, int do_map) to
ifcvf_dma_map(struct ifcvf_internal *internal, bool do_map), and use "true" or "false" when calling it.
This would align with vdpa_enable_vfio_intr(). In your next version patch, you can also change the "1", "0" parameter to
"true", "false" when calling vdpa_enable_vfio_intr().
BRs,
Xiao
