Fengguang Wu, Mel Gorman and James Bottomley did all the legwork to track the root cause of the problem. This fix and entire commit log is shamelessly copied from them with one extra detail to change a dubious runtime use of ATOMIC_INIT() to atomic_set() in drivers/char/mspec.c 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.
