Yes, they are available on RHEL 6.x.
"since 2.6.35, xfs had a new mount option '-o delaylog', which
improved a lot metadata operations. From 2.6.39 this option is on by
default"
Is this a redhat specific feature? Again, man mount says nothing about
those options.
You're right that it doesn't seem to be properly listed in the list of
options, but it's discussed
