#syz set subsystems: arm
ip6_output() is recursed 9 times in the stack.
Eric pointed out that:
#define MAX_NEST_DEV 8
#define XMIT_RECURSION_LIMIT 8
So net stack can legitimately do this recursion and arm stack is 2x
smaller than x86_64 stack (8K instead of 16K).
Should arm stack be increased? Or MAX_NEST_DEV/XMIT_RECURSION_LIMIT
reduced for arm?
Note: KASAN is not enabled in the config.

Do we guarantee that order-2 allocations will succeed on a 4k page-
sized system? It seems it would be a doubling of the chances of
failure.
Another solution would be to use vmalloc, but then I'd start to
worry about vmalloc space. With a 16k vmalloc allocation (plus
guard page and alignment) that'll be 32k per thread, and 32k
threads would be 512M, which for a 3G:1G user/kernel split is
too way too big, so I don't think vmalloc is an option.
Is there nothing that net can do to reduce its stack usage?
