Subject: [PATCH v1 0/2] mm/memory_hotplug: handle memblocks only with CONFIG_ARCH_KEEP_MEMBLOCK
Date: Wed, 22 Apr 2020 17:53:51 +0200 [thread overview]
Message-ID: <20200422155353.25381-1-david@redhat.com> (raw)
While working on some other cleanups I stumbled over the creation/removal
of memblocks in hotplug code and wondered why we still need that. Turns
out, we only need that handling with CONFIG_ARCH_KEEP_MEMBLOCK.
Gave it a quick test on x86-64.
RFC -> v1:
- Added ACKs
- Rephrased subject/description of patch #1
- Use IS_ENABLED() instead of ifdefs in patch #2

mm/memory_hotplug: set node_start_pfn of hotadded pgdat to 0
mm/memory_hotplug: handle memblocks only with
CONFIG_ARCH_KEEP_MEMBLOCK
