An interesting quandary has arose on the Linux kernel mailing list over maintainership of old, unmaintained code within the Linux kernel. Someone has stepped up to maintain an old, very rare file-system driver but admittedly doesn't even use it and just submitted basic fixes. Or is it just better removing that old code?

As the discussions continue among developers over potentially branching off some of the older Mesa drivers, the AMD R600 Gallium3D driver saw 59 commits on Sunday to Mesa 26.2. Making this code restructuring and code cleaning all the more notable is that the improvements to this old AMD Radeon graphics driver was done in part by GitHub Copilot.

In addition to the SpacemiT K1 and K3 RISC-V SoC Device Tree updates sent out last week, the RISC-V T-HEAD Device Tree "DT" changes were also sent out last week ahead of the upcoming Linux 7.2 kernel merge window.
