The patch titled
Subject: ext4: pass the inode to ext4_mpage_readpages
has been removed from the -mm tree. Its filename was
ext4-pass-the-inode-to-ext4_mpage_readpages.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: "Matthew Wilcox (Oracle)" <willy@xxxxxxxxxxxxx>
Subject: ext4: pass the inode to ext4_mpage_readpages
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.
