Ok, it is possible the 0-page alloc failed because NOHIGHIO was disabled, Linus's fix being less finegrined than mine could also lead more easily to 0-page alloc failed.
However failing bounce-allocation is not important since we have the reserved pool for those allocations. Not having to use the reserved pool only allows an higher amount of I/O in parallel. This is why I said we could have dropped the NOHIGHIO logic in first place if we wanted to go the non finegrined way.
