[PATCH v8 23/25] f2fs: Pass the inode to f2fs_mpage_readpages

From: Matthew Wilcox
Date: Tue Feb 25 2020 - 16:48:47 EST


From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>

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.
