From 47fbc518a4b5c9a949f7cab8b14a00d3549bf138 Mon Sep 17 00:00:00 2001 From: Jason Baron Date: Thu, 28 Jun 2012 15:05:02 -0400 Subject: [PATCH] jump label: Remove static_branch() Remove the obsolete static_branch() interface, since the supported interface is now static_key_false()/true() - which is used by all in-tree code. See commit: c5905afb0e ("static keys: Introduce 'struct static_key', static_key_true()/false() and static_key_slow_[inc|dec]()").
