[PATCH] mm: fix up sparse warning in gfpflags_allow_blocking

From: Jeff Layton
Date: Fri Nov 20 2015 - 09:41:12 EST

sparse says:

include/linux/gfp.h:274:26: warning: incorrect type in return expression (different base types)
include/linux/gfp.h:274:26: expected bool
include/linux/gfp.h:274:26: got restricted gfp_t

...add a forced cast to silence the warning.
