For what it's worth, you can try to pry this info out of Oracle's
RedPatch <https://oss.oracle.com/projects/RedPatch/>, which actually
doesn't look all that active anymore recently, but given that it's
Oracle, one cannot seriously be surprised about anything.

The thing is, that RHEL XFS and mainline XFS seem to have drifted
apart a good deal, and as result, for an outsider, it is very
difficult to correlate patches between the two branches.
