[PATCH 1/2] mm: memblock: add missing HugeTLB flag name

From: Meijing Zhao

Date: Wed Aug 19 2026 - 03:55:43 EST


From: Meijing Zhao <zhaomeijing@xxxxxxxxxxx>

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.

Fixes: 7d163a75f821 ("memblock: make HugeTLB bootmem allocation work with KHO")
