Official description
In the Linux kernel, the following vulnerability has been resolved:
ocfs2: handle a symlink read error correctly
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!
