    Add noalign suboptions to -d and -r to allow auto-stripe-alignment to be switched off.

The noalign option has been in mkfs since 2005, so it's most
certainly supported on RHEL6.

Looking at the man page history, I forgot that it wasn't documented
until 2013 and hence is missing from the RHEL6 man page, so I can
understand why you might be saying this.
