+         Originally UBIFS did not support atime, because it looked like a bad idea due
+         increased flash wear. This option adds atime support and it is disabled by default
+         to preserve the old behavior. If you enable this option, UBIFS starts updating atime,
+         which means that file-system read operations will cause writes (inode atime
+         updates). This may affect file-system performance and increase flash device wear,
+         so be careful. How often atime is updated depends on the selected strategy:
+         strictatime is the "heavy", relatime is "lighter", etc.
