From cd8d860dcce906cd477be7d0648ba6f56a52eaa6 Mon Sep 17 00:00:00 2001 From: Boris Ostrovsky Date: Tue, 28 Feb 2017 11:32:22 -0500 Subject: [PATCH] jump_label: Fix anonymous union initialization Pre-4.6 gcc do not allow direct static initialization of members of anonymous structs/unions. After commit 3821fd35b58d ("jump_label: Reduce the size of struct static_key") STATIC_KEY_INIT_{TRUE|FALSE} definitions cannot be compiled with those older compilers. Placing initializers inside curved brackets works around this problem.
