This is a K&R level C construct.
It is discouraged in style(9) because it makes it hard to find
declarations. However, it is used in the kernel in a number of
places.
I personally really dislike the style (and yes, I know all the
arguments for it). If you really want something that complex inside a
block to need block scoped variables, then that really argues for a
function oft times...
