Subject: [merged] mm-memory_hotplug-clean-up-try_offline_node.patch removed from -mm tree
Date: Thu, 24 Mar 2022 18:32:44 -0700	[thread overview]
Message-ID: <20220325013244.E5FE9C340ED@smtp.kernel.org> (raw)


The patch titled
     Subject: mm/memory_hotplug: clean up try_offline_node
has been removed from the -mm tree.  Its filename was
     mm-memory_hotplug-clean-up-try_offline_node.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Miaohe Lin <linmiaohe@huawei.com>
Subject: mm/memory_hotplug: clean up try_offline_node

We can use helper macro node_spanned_pages to check whether node spans
pages.  And we can change the parameter of check_cpu_on_node to nid as
that's what it really cares.  Thus we can further get rid of the local
variable pgdat and improve the readability a bit.
