Following up to feedback on his merge plans [story], Andrew Morton [interview] posted an updated summary of what he is pushing upstream for inclusion in the upcoming 2.6.22 kernel. His list included, "a few serial bits, a few pcmcia bits, one little security patch, the blackfin architecture, small h8300 update, small alpha update, swsusp updates, m68k bits, and lots of UML updates." He also noted that he'll push some of the memory management queue including, "an enhancement to /proc/pid/smaps to permit monitoring of a running program's working set. The SLUB allocator, it's pretty green but I do want to push ahead with this pretty aggressively with a view to replacing slab altogether. Generic pagetable quicklist management. We have x86_64 and ia64 and sparc64 implementations, but I'll only include David's sparc64 implementation here. I'll send the x86_64 and ia64 implementations through maintainers."
