I think we absolutely need something like this, and I'm sick and tired of the people just claiming there is no problem.
From the user POV I don't care if aligned allocations need a new GFP_ALIGNED flag or not, but as far as I can tell the latter will probably cause more overhead in practice than not having it.
So unless someone comes up with a better counter proposal to provide aligned kmalloc of some form that doesn't require a giant amount of boilerplate code in the users:
