[$] The next steps for the maple tree

The maple tree data structure was addedduring the 6.1 development cycle; since then, it has taken itsplace at the core of the kernel's memory-management subsystem.Unsurprisingly, work on maple trees is not yet done. Maple-tree maintainerLiam Howlett ran a session in the memory-management track of the 2024 Linux Storage,Filesystem, Memory-Management and BPF Summit to discuss the currentstate of the maple tree and which features can be expected next.
