From: David Hildenbrand Date: Fri, 26 Feb 2021 01:17:17 +0000 (-0800) Subject: mm/memory_hotplug: MEMHP_MERGE_RESOURCE -> MHP_MERGE_RESOURCE X-Git-Tag: v5.15~1629^2~87 X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=26011267e1a7ddaab50b5f81b402ca3e7fc2887c;p=mirror_ubuntu-kernels.git mm/memory_hotplug: MEMHP_MERGE_RESOURCE -> MHP_MERGE_RESOURCE Let's make "MEMHP_MERGE_RESOURCE" consistent with "MHP_NONE", "mhp_t" and "mhp_flags". As discussed recently [1], "mhp" is our internal acronym for memory hotplug now.
