Subject: [PATCH v8 23/25] f2fs: Pass the inode to f2fs_mpage_readpages
Date: Tue, 25 Feb 2020 13:48:36 -0800 [thread overview]
Message-ID: <20200225214838.30017-24-willy@infradead.org> (raw)
In-Reply-To: <20200225214838.30017-1-willy@infradead.org>
From: "Matthew Wilcox (Oracle)" <willy@infradead.org>
This function now only uses the mapping argument to look up the inode,
and both callers already have the inode, so just pass the inode instead
of the mapping.
Signed-off-by: Matthew Wilcox (Oracle) <willy@infradead.org>
