From dca496451bddea9aa87b7510dc2eb413d1a19dfd Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 2 Sep 2014 14:46:01 -0400 Subject: percpu: move common parts out of pcpu_[de]populate_chunk() percpu-vm and percpu-km implement separate versions of pcpu_[de]populate_chunk() and some part which is or should be common are currently in the specific implementations. Make the following changes. * Allocate area clearing is moved from the pcpu_populate_chunk() implementations to pcpu_alloc(). This makes percpu-km's version noop. * Quick exit tests in pcpu_[de]populate_chunk() of percpu-vm are moved to their respective callers so that they are applied to percpu-km too. This doesn't make any meaningful difference as both functions are noop for percpu-km; however, this is more consistent and will help implementing atomic allocation support.
