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' -- cgit v1.2.3-54-g00ecf
