I'm perfectly aware the fs tends to be the less correct places in terms
of allocations, and luckily it's not an heavy memory user, so I still
have to see a deadlock in getblk or create_buffers or similar. It's
mostly a correctness issue (math proof it can't deadlock, right now it
can if more tasks all get stuck in getblk at the same time during a hard
oom condition etc..).
