A purely janitorial patchset. A fairly common pattern is to take a list, remove every object from it and do something with this object - usually kfree() some variant. A stupid grep identified roughly 300 instances, with many more hidden behind more complicated patterns to achieve the same end results.
This patchset moves the boilerplate code into list.h and uses it in a few example places. Diffstat is pretty clear and imo the code is improved as well. Drawback is that object size is growing. I think an ideal compiler should be able to optimize all the overhead away, but 4.7 just isn't there yet. Or maybe I just messed up - patches are only compile-tested after all. Comments/ideas are welcome.
