5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox (Oracle) <willy@xxxxxxxxxxxxx>
commit 0b768a9610c6de9811c6d33900bebfb665192ee1 upstream.
The pagecache handles readpage failing by itself; it doesn't want
filesystems to remove pages from under it.
