Subject: [PATCH v10 15/18] mm: remove extra vma_numab_state_init() call
Date: Thu, 13 Feb 2025 14:46:52 -0800	[thread overview]
Message-ID: <20250213224655.1680278-16-surenb@google.com> (raw)
In-Reply-To: <20250213224655.1680278-1-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().
