Andrew/Nick/Ingo,
Here's a different version of the patch that tries to handle mem
allocation failures in build_sched_domains by bailing out and cleaning up
thus-far allocated memory. The patch has a direct consequence that we disable
load balancing completely (even at sibling level) upon *any* memory allocation
failure. Is that acceptable?
I guess so. Ideal solution would be to make all required allocations first,
then fail the build_sched_domains and fall back to the old structure. But
I guess that gets pretty complicated.
In reality (and after your patch 2/4), I don't think the page allocator will
ever fail any of these allocations. In that case, would it be simpler just
to add a __GFP_NOFAIL here and forget about it?
