Subject: [PATCH 1/3] mm/vmalloc: group xa_init with vbq field initializations
Date: Mon, 14 Sep 2026 11:34:00 +0800 [thread overview]
Message-ID: <20260914-vmalloc_study-v1-1-526f68559706@linux.dev> (raw)
In-Reply-To: <20260914-vmalloc_study-v1-0-526f68559706@linux.dev>
From: Ye Liu <liuye@kylinos.cn>
Move xa_init() next to the other vbq field initializations instead of
after the unrelated vfree_deferred setup.
