KernelTrap.org: Interview With Andrew Morton

Feb 12, 2002, 19:32 (1 Talkback[s])

[ Thanks to Jeremy for this link. ]

Kerneltrap has spoken with Linux kernel hacker, Andrew Morton. His contributions cover a wide range of kernel components, including ext3 on 2.4 and the low-latency patch. Currently he works for moxi.com:
"JA: Do you have plans to get your low-latency patch into the 2.5 kernel?

Andrew Morton: Not in its present form. First I'd like to see a general consensus that Linux should become a low-latency OS. With that, we can then merge the preempt patch and start work on carefully and cleanly addressing the various long-held locks. Simply dropping locks and then cleaning up the mess is not a very satisfactory solution - better would be to change the local locking design, or to speed the locked code up by a factor of one hundred. The latter usually is not possible.

I do not plan on spending much time on 2.5 for a while. I'd rather invest effort in things which are more immediately needed by people. There are still many correctness, performance and quality-of-implementation issues to be addressed in 2.4.x. The 2.4.x core has only stabilized very recently and there remains quite a bit of tuning and mop-up work."
