Linux, dev-mapper: How to mount a folder with different options than parent folder

I'm using CentOS 7.1 with device-mapper, and /home mounted as

/dev/mapper/centos-home on /home type xfs (rw,relatime,seclabel,attr2,inode64,noquota)

I'd like to include in fstab an entry for mounting /home/xyz with different options than those for /home (e.g. noatime)

I've tried on a PC that doesn't have dev-mapper:

mkdir /xyz
mount --bind /home/xyz/ /xyz -o noatime

Would the next line in fstab work? Is there an easier (more simple) way? Do I need to run some other command for Device Mapper?

/dev/mapper/centos-home-xyz /home/xyz xfs noatime

Device-mapper has nothing to do with it. What is the business problem you are trying to solve? – Michael Hampton Aug 05 '15 at 16:11
Hi Michael, I've /home mounted as described in the first line (one of it's options is relatime), I'd like to have /home/xyz mounted with option noatime – Diego Shevek Aug 05 '15 at 17:05
That's not the business problem you're trying to solve. – Michael Hampton Aug 05 '15 at 17:08
