exFAT's access time has 2s granularity and is rounded down. This can cause problems, e.g.: if real access times are: time1=2 and time2=7, then 7 - 2 = 5; but exfat_atime(7) - exfat_atime(2) => 6 - 2 = 4 which is less than expected delay. To fix this, even (delay - 1s) should be considered as a valid result for exFAT.
