Btw, after you add the check to vduse_validate_config() you can test that it silences the Smatch warning by doing: kchecker --info drivers/vdpa/vdpa_user/vduse_dev.c | tee out ~/smatch/smatch_data/db/reload_partial.sh out kchecker drivers/vdpa/vdpa_user/vduse_dev.c You might need to do a second --info and reload for the changes to propagate. regards, dan carpenter _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
