Subject: [PATCH v3 02/12] nilfs2: drop usage of page_index
Date: Tue, 30 Apr 2024 03:04:50 +0800 [thread overview]
Message-ID: <20240429190500.30979-3-ryncsn@gmail.com> (raw)
In-Reply-To: <20240429190500.30979-1-ryncsn@gmail.com>
From: Kairui Song <kasong@tencent.com>
page_index is only for mixed usage of page cache and swap cache, for
pure page cache usage, the caller can just use page->index instead.
It can't be a swap cache page here (being part of buffer head),
so just drop it, also convert it to use folio.
