Subject: Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts
From: Mel Gorman <[email protected]>
commit 67a806d9499353fabd5b5ff07337f3aa88a1c3ba upstream.
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.
