From be66687a2e6eeb6d2b369eb2fb7406ca00610829 Mon Sep 17 00:00:00 2001 From: Mel Gorman Date: Mon, 23 Jul 2012 12:16:19 +0100 Subject: PARISC: Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the casts commit bba3d8c3b3c0f2123be5bc687d1cddc13437c923 upstream. The following build error occured during a parisc build with swap-over-NFS patches applied. net/core/sock.c:274:36: error: initializer element is not constant net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks') 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.
