Minutes for November 15, 2002 LSE Con. Call I. Hanna Linder - epoll epoll stands for event poll. It was written by Davide Libenzi originally last year. Linus didn't like the interface being in /dev so I proposed a system call interface instead. Since this is not Davide's paid full time work we were expecting to have to make the code changes internally. However, Davide spent his weekends and evenings working on it and had it done much quicker than I would have. You may remember a long thread in October between a few people on lkml. Most people stopped reading it but the gist of the complaints had to do with the way Davide had chosen to do registration of events of interest and notification of events. To summarize the way it works epoll does not have to linearly search all fd's looking for events instead it uses a callback mechanism to notify when events are ready. This is especially useful in cases such as web hosting where only a few connections are active so you only are notified of the active sockets. I am working on a 2.4 backport. II. Rick Lindsley - Currently there is no easy way to get the disk statistics out. Everything Rick needs is now in 2.5.47 and he expects to be done porting the tools (iostat, sar) in a few days. Then Rick is committed to getting the 2.4 disk statistics in based on Marcelo's input of what he wants to see (which he is still waiting to receive). The carrier grade people need to have this. Rick is currently working with some people from OSTL on a sysfs potential bug. Stay tuned for more info about it on the 2.5 bug tracker database. III. Martin Bligh - 2.5 bugtracker It was launched 1.5 days ago, OSDL is hosting it and IBM does some administration. The goal is to help stabilize 2.5 as quickly as possible. The address is bugme.osdl.org (with a cname from bugzilla.kernel.org if you prefer). You can search without an account. Creating a new account is simple enough. Currently there are 300 people signed up and about 60 bugs. If you log bugs against -mm or -ac trees dont put the networking guys in as owner use mbligh@aracnet.com instead because they aren't as interested in supporting those non mainline tress right now. We have quite a few maintainers signed up already to maintain their own areas. If there are unmaintained areas in a week or two please volunteer to maintain them. For now the biggest help is to feed bugs into the database. When submitting bugs make sure to run oops thru ksymoops or turn on kksymoops to do it for you automatically. ----- minutes compiled by Hanna Linder (hannal@us.ibm.com)
