Hmm. Since memory allocation is first tried with GFP_ATOMIC set and upon failure retried in background, this seems like a situation which might happen during normal use. If that already indicates a severe problem, why retry in background at all?
It should be tried in the background first at 70% and only when that fails would we hit the 100% case and then we will try it with GFP_ATOMIC. If that fails then the insertion will fail.
