Andrey tells me he uses this file to create artificial out-of-memory
conditions when testing drivers.
I've poked various numbers in there but I can't seem to force an OOM
condition in the driver. Having read the description in
Documentation/sysctl/vm.txt it appears that I need to run another app
which will exhaust vm...
So. Could someone please tell me what to do to force an alloc_skb OOM
condition within a network device driver?
Ta.
