I am running with this reverted now, and I cannot reproduce the
khugepage going overboard anymore.

I tried hard since 2 days now, no chance to reproduce.
Before firefox or shotwell went into boom mode, but not now.
(For now!)

If you want, I can compile a "default" kernel without the above commit
reverted, and turn on STACKTRACE (I have turned it one for *all* future
kernels I compile ;-)

I also didn't try the patch you send me, just the revert from above.

Please let me know which other experiments you want to see.

Thanks

Norbert
