Subject: [PATCH 04/14] mm, memory_hotplug: get rid of is_zone_device_section
Date: Mon, 15 May 2017 10:58:17 +0200	[thread overview]
Message-ID: <20170515085827.16474-5-mhocko@kernel.org> (raw)
In-Reply-To: <20170515085827.16474-1-mhocko@kernel.org>

From: Michal Hocko <mhocko@suse.com>

device memory hotplug hooks into regular memory hotplug only half way.
It needs memory sections to track struct pages but there is no
need/desire to associate those sections with memory blocks and export
them to the userspace via sysfs because they cannot be onlined anyway.

This is currently expressed by for_device argument to arch_add_memory
which then makes sure to associate the given memory range with
ZONE_DEVICE. register_new_memory then relies on is_zone_device_section
to distinguish special memory hotplug from the regular one. While this
works now, later patches in this series want to move __add_zone outside
of arch_add_memory path so we have to come up with something else.

Add want_memblock down the __add_pages path and use it to control
whether the section->memblock association should be done. arch_add_memory
then just trivially want memblock for everything but for_device hotplug.

remove_memory_section doesn't need is_zone_device_section either. We can
simply skip all the memblock specific cleanup if there is no memblock
for the given section.

This shouldn't introduce any functional change.

Changes since v1
- return 0 if want_memblock == 0 from __add_section as per Jerome Glisse

Changes since v2
- fix remove_memory_section unlock on find_memory_block failure
  as per Jerome - spotted by Evgeny Baskakov
