Subject: [PATCH v6 01/10] mm: memblock: add missing HugeTLB flag name
Date: Wed,  2 Sep 2026 15:31:07 +0800	[thread overview]
Message-ID: <20260902073116.802752-2-chenwandun1@gmail.com> (raw)
In-Reply-To: <20260902073116.802752-1-chenwandun1@gmail.com>

From: Meijing Zhao <zhaomeijing@lixiang.com>

Commit 7d163a75f821 ("memblock: make HugeTLB bootmem allocation work
with KHO") added MEMBLOCK_RSRV_HUGETLB but did not add the corresponding
entry to flagname[]. As a result, memblock debugfs cannot report the
flag by name.

Add the missing RSV_HUGETLB entry.
