CVE-2022-48668 Information

Description

In the Linux kernel the following vulnerability has been resolved:

smb3: fix temporary data corruption in collapse range

collapse range doesn’t discard the affected cached region so can risk temporarily corrupting the file data. This fixes xfstest generic/031

I also decided to merge a minor cleanup to this into the same patch (avoiding rereading inode size repeatedly unnecessarily) to make it clearer.
