Why are we bothering with any of this, given that
: Luckily, private_data is NULL for address spaces in all such cases
: today but, there is no guarantee this will continue.

Even though 58b6e5e8f1ad was inappropriately backported, the above

address space in inode for resv_map pointer" actually solve?
And yes, some review of this would be nice
