Date: Thu, 02 Nov 2017 05:38:33 +0800 From: "Yang Shi" <yang.s@...baba-inc.com> To: mhocko@...nel.org, akpm@...ux-foundation.org Cc: "Yang Shi" <yang.s@...baba-inc.com>, <linux-mm@...ck.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH] mm: use in_atomic() in print_vma_addr() commit 3e51f3c4004c9b01f66da03214a3e206f5ed627b ("sched/preempt: Remove PREEMPT_ACTIVE unmasking off in_atomic()") makes in_atomic() just check the preempt count, so it is not necessary to use preempt_count() in print_vma_addr() any more. Replace preempt_count() to in_atomic() which is a generic API for checking atomic context.
