Subject: [PATCH v8 13/16] mm: remove extra vma_numab_state_init() call
Date: Wed,  8 Jan 2025 18:30:22 -0800	[thread overview]
Message-ID: <20250109023025.2242447-14-surenb@google.com> (raw)
In-Reply-To: <20250109023025.2242447-1-surenb@google.com>

vma_init() already memset's the whole vm_area_struct to 0, so there is
no need to an additional vma_numab_state_init().
