Does it guarantee delay time strictly? It seems that nandsim would allocate memory using vmalloc function. those memory spaces could be swapped out. When I set access_delay to 20us, If required data was in hard disk, nandsim could not finish required operation in given delay time because read data from hard disk takes longer time than 20us. How resolve this problem in nandsim? -- Best regards, Kang-Nyeon Kim
