    // why re enabling interrupt here ? Because an interrupt can occur between the lock acquire and
    // int 101 and the interrupt won't be able to handle the lock.

    // Interrupts remain disabled (IF=0 from the saved RFLAGS at the int $101 point).
    // The syscall return path (iretq) restores the user RFLAGS with IF=1.
