Subject: [PATCH v2 03/16] include/linux/huge_mm.h: define is_huge_zero_pmd() if !CONFIG_TRANSPARENT_HUGEPAGE
Date: Tue, 13 Apr 2021 00:56:20 -0600	[thread overview]
Message-ID: <20210413065633.2782273-4-yuzhao@google.com> (raw)
In-Reply-To: <20210413065633.2782273-1-yuzhao@google.com>

Currently is_huge_zero_pmd() only exists when
CONFIG_TRANSPARENT_HUGEPAGE=y. This patch adds the function for
!CONFIG_TRANSPARENT_HUGEPAGE.
