Subject: [RFC PATCH v2 01/12] arch: mm: rename FORCE_MAX_ZONEORDER to ARCH_FORCE_MAX_ORDER
Date: Thu, 11 Aug 2022 19:16:32 -0400 [thread overview]
Message-ID: <20220811231643.1012912-2-zi.yan@sent.com> (raw)
In-Reply-To: <20220811231643.1012912-1-zi.yan@sent.com>
From: Zi Yan <ziy@nvidia.com>
This Kconfig option is used by individual arch to set its desired
MAX_ORDER. Rename it to reflect its actual use.
