 -> Assertion `t->regs().syscall_result_signed() == -syscall_state.expect_errno' failed to hold. Expected ENOSYS for 'futex_waitv' but got result -22 (errno EINVAL); execution of syscall unsupported by rr

Can we expect support for this syscall anytime soonish or is it not possible? Also could i run my program with an older kernel perhaps?
