ubifs: introduce UBIFS_ATIME_SUPPORT to ubifs
To make ubifs support atime flexily, this commit introduces a Kconfig option named as UBIFS_ATIME_SUPPORT. With UBIFS_ATIME_SUPPORT=n: ubifs keeps the full compatibility to no_atime from the start of ubifs. =================UBIFS_ATIME_SUPPORT=n======================= -o - no atime -o atime - no atime -o noatime - no atime -o relatime - no atime -o strictatime - no atime -o lazyatime - no atime With UBIFS_ATIME_SUPPORT=y: ubifs supports the atime same with other main stream file systems. =================UBIFS_ATIME_SUPPORT=y======================= -o - default behavior (relatime currently) -o atime - atime support -o noatime - no atime support -o relatime - relative atime support -o strictatime - strict atime support -o lazyatime - lazy atime support Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Reviewed-by: Richard Weinberger <richard@nod.at> Signed-off-by: Richard Weinberger <richard@nod.at>
