It's logical but afaik unconventional that none of the flex_array
kerneldoc actually documents the `struct flex_array *fa' argument.
We're all waiting with bated breath to see who will be the first to use

Sometime we'll need to move flex_array.o from lib-y to obj-y and fill
it up with EXPORT_SYMBOL()s. 2.6.32 I expect.
