These 2 exercise independent code paths and need different arguments. After this change, you call: cpudl_clear(cp, cpu); cpudl_set(cp, cpu, dl); instead of: cpudl_set(cp, cpu, 0 /* dl */, 0 /* is_valid */); cpudl_set(cp, cpu, dl, 1 /* is_valid */); Signed-off-by: Tommaso Cucinotta <tommaso.cucinotta@sssup.it> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Luca Abeni <luca.abeni@unitn.it> Reviewed-by: Juri Lelli <juri.lelli@arm.com> Cc: Juri Lelli <juri.lelli@gmail.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: linux-dl@retis.sssup.it Link: http://lkml.kernel.org/r/1471184828-12644-4-git-send-email-tommaso.cucinotta@sssup.it Signed-off-by: Ingo Molnar <mingo@kernel.org>
