5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthew Wilcox (Oracle) willy@infradead.org
commit 2b4c2094da6d84e69b843dd3317902e977bf64bd upstream.
Patch series "Convert ocfs2 to use folios".
Mark did a conversion of ocfs2 to use folios and sent it to me as a giant patch for review ;-)
So I've redone it as individual patches, and credited Mark for the patches where his code is substantially the same. It's not a bad way to do it; his patch had some bugs and my patches had some bugs. Hopefully all our bugs were different from each other. And hopefully Mark likes all the changes I made to his code!
