The patch titled
Subject: mm/memory_hotplug: is_mem_section_removable() can return bool
has been removed from the -mm tree. Its filename was
mm-memory_hotplug-is_mem_section_removable-can-be-boolean.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Yaowei Bai <baiyaowei@xxxxxxxxxxxxxxxxxxxx>
Subject: mm/memory_hotplug: is_mem_section_removable() can return bool
Make is_mem_section_removable() return bool to improve readability due to
this particular function only using either one or zero as its return
value.
