Any mailing list for Linux internals other than LKML?

[Yong Huang]

The Linux kernel mailing list (LKML) has lots of traffic, mostly 
about code to patch the kernel. Is there a mailing list or online 
web forum where people talk about Linux internals by just reading 
kernel code? For UNIX, the comp.unix.internals newsgroup does that 
(or "did" that, due to uncontrolled growth of spams in the past 
one or two years). I'd like to know something similar but just for 
Linux. Thanks.

(In case you ask if I have a specific question, for now yes. 
`ipcs -u | grep '^segments allocated'' gives a wrong number than 
`ipcs -m' shows, and I'm tracking that down.)
