Hi Miklos.
Looks like you have found the problem despite your skepticism. Well done.
I've been trying to figure out how to implement your idea of only
blocking on a single page allocation.
I'll attach the patch that I've come up with, however I'm
not very confident of it.
I need to call cpu_cache_get both directly and via slab_force_alloc
in a context where we could conceivably be rescheduled onto another
CPU. This feels wrong, but I cannot see that it will actually be
a problem.
Have you thought about an implementation?
