Fixes for 5.18-rc1: - Fix some incorrect mapping state being passed to iomap during COW - Don't create bogus selinux audit messages when deciding to degrade gracefully due to lack of privilege - Fix setattr implementation to use VFS helpers so that we drop setgid consistently with the other filesystems - Fix link/unlink/rename to check quota limits - Constify xfs_name_dotdot to prevent abuse of in-kernel symbols
