[$] Backporting XFS fixes to stable

Backporting fixes to stable kernels is an ongoing process that, in general,is handled by the stable maintainers or the developers of the fixes.However, due to some unhappiness in the XFS developmentcommunity with the process of handling stable fixes for that filesystem,a different process has come about for backporting XFS patches to thestable kernels. The three developers doing that work, Leah Rumancik, AmirGoldstein, and Chandan Babu Rajendra, led a plenary session at the 2023 Linux Storage, Filesystem,Memory-Management and BPF Summit (with Rajendraparticipating remotely) to discuss that process.
