Help text

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.

If unsure, say 'N'
