Yes. Or even use the existing call, with a flag not to touch the comm altogether. That way the calling process could just: fork(); prctl(PR_SET_NAME, "lalala"); execveat(..., AT_KEEP_PR_NAME); and be done with it.

Simple solution
Maybe even the pathname argument could be repurposed to become comm with AT_EMPTY_PATH (plus/or another new flag to control this new behavior), because normally it's an empty string with AT_EMPTY_PATH? That would avoid the need for prctl().
