Subject: [PATCH 0/2] mm: memblock: fix debugfs flag reporting
Date: Wed, 19 Aug 2026 15:54:20 +0800 [thread overview]
Message-ID: <20260819075422.2387980-1-zhaomeijing100@gmail.com> (raw)
From: Meijing Zhao <zhaomeijing@lixiang.com>
The memblock debugfs interface has two issues when reporting region
flags. MEMBLOCK_RSRV_HUGETLB has no corresponding name, and regions
with multiple flags only show the lowest set bit.
Add the missing HugeTLB flag name and make memblock_debug_show() print
all flags. With the series applied, a HugeTLB bootmem reservation is
reported as:
RSV_KERN|RSV_HUGETLB
Meijing Zhao (2):
mm: memblock: add missing HugeTLB flag name
mm: memblock: show all region flags in debugfs
