Setting noatime via mount options vs no atime updates (A) file attribute

From man chattr > When a file with the 'A' attribute set is accessed, its atime record > is not modified. This avoids a certain amount of disk I/O for laptop > systems. However when I am remounting a filesystem with the noatime mount option: [root@localhost ~]# mount -o remount,noatime /dev/sdb1 /newfs/ creating a file in it [root@localhost ~]# cd /newfs/ [root@localhost newfs]# touch myfile and getting its file attributes: [root@localhost newfs]# lsattr myfile -------------e-- myfile the A file attribute is not set despite the fact. Is this the expected behavior?
