Well:
- the fragmentation problems have been hidden fairly well by
  making the dcache better prunable and by allocating less
  inodes on small systems
- some swap count 'overflow' has been fixed by Stephen
  (there was a leak on 127+ users of one page) -- has this been
  merged?
- Stephen implemented swap partitions of up to 2 GB -- not yet merged
- Bill Hawes did an awful lot of debugging, he fixed several
  (all?) cases of "found a writable swap cache page"
- I updated some documentation and am busy writing more (for 2.2,
  documentation has my priority)
- I am working on proper Out-of-VM process killing code (which
  might even work by now :-)
- DaveM is working on a fast hashing scheme for VMAs (read the
  "2.1 makes Electric Fence 22x slower" thread on linux-kernel)
- Eric has been busy coding SHMfs and doing dirty pages in the
  page cache -- scheduled for 2.3 integrations
- Linus has announced a definite code freeze (at 2.1.115)

Look at http://roadrunner.swansea.uk.linux.org/jobs.shtml
or http://www.phys.uu.nl/~riel/mm-patch/todo.html for more
info on what to do...

btw, did you have a nice holiday?

Rik.
