-What: init_mm export
-When: 2.6.26
-Why: Not used in-tree. The current out-of-tree users used it to
- work around problems in the CPA code which should be resolved
- by now. One usecase was described to provide verification code
- of the CPA operation. That's a good idea in general, but such
- code / infrastructure should be in the kernel and not in some
- out-of-tree driver.
