g2k16 Hackathon Report: Otto Moerbeek on back to malloc, and more

Next in the g2k16 series is the Otto Moerbeek's report. Otto writes,
It has been a while since I was at a hackathon, due to various reasons
the last hackathon I attended was in 2008 where I did commit my
implementation of malloc. During the years, various improvements to my
malloc were done, both by others and myself.
But now, 8 years later I
came back to to commit a important change: make malloc more friendly
to multi-threaded programs. Most of the actual work had been done
during the months before the hackathon, but in Cambridge I did the
last checks, got my OK's and committed! Of course this is not the last
commit in this areas, the current approach is simple (but effective),
it can be improved after it has been proven to be stable.
Apart from that I worked on some changes to newfs(8), disklabel(8) and
fsck_ffs(8) to make the code to find alternative superblocks (which is
used if the primary superblock is corrupted) work better. Testing that
code takes quite some time, but it was good to see my manually
corrupted filesystems come back to clean state.
A hackathon is not complete without pub and restaurant visits and some
tourist activities, we went punting on the Cam. All in all, I had a
very good time, it was really nice to meet other developers
in person (again). In the futue, I hope to be able to come more often!
Thanks for the report, Otto! And thanks for continuing to provide excellent code to our favorite operating system!
