Subject: Need to potentially watch stack usage for ext4 and AIO...

On a 32-bit system, while running aio-stress, I got the following kernel
message:

aio-stress used greatest stack depth: 372 bytes left

That's a bit close for comfort; we may want to see if we have some
especially piggy on-stack allocations on the AIO code paths.
