What did you do?

I am using github.com/ii64/gouring library, i was using go 1.22 and it was working fine but after updating go version 1.22 to 1.23.0 it is giving compilation error.

What did you see happen?

After updating to 1.23.0 i am getting error "invalid reference to syscall.munmap"

when i see inside library there were go:linkname used for syscall.munmap

//go:linkname munmap syscall.munmap
func munmap(addr unsafe.Pointer, length uintptr) (err error)

What did you expect to see?

I was not expecting compilation error

@rsc please help in the same
