[$] Toward a real "too small to fail" rule

Description:
Kernel developers have long been told that any attempt to allocate memory
might fail, so their code must be prepared for memory to be unavailable. Informally, though, the kernel's memory-management subsystem implements a policy whereby requests below a certain size will not fail (in process
context, at least), regardless of
how tight memory may be. A recent discussion on the linux-mm list has
looked at the idea of making the "too small to
fail" rule a policy that developers can rely on.
