The following build error occurred during an alpha build:

net/core/sock.c:274:36: error: initializer element is not constant

Dave Anglin says:

Here is the line in sock.i:

struct static_key memalloc_socks = ((struct static_key) { .enabled =
((atomic_t) { (0) }) });

The above line contains two compound literals.  It also uses a designated
initializer to initialize the field enabled.  A compound literal is not a
constant expression.

The location of the above statement isn't fully clear, but if a compound
literal occurs outside the body of a function, the initializer list must
consist of constant expressions.

I'll remvoe the Cc:stable from this one - the regression is post-3.5.
