| |
Alright, since my last e-mail generated no interest, I thought I'd refine my queries:
1. wake_up_interruptible()
I am reading http://www.citi.umich.edu/projects/linux-scalability/reports/accept.html and the my question is what solution to the "thundering herd" problem was eventually chosen and is implemented in the 2.4.x kernels? Where can I find more specific information on this implementation? Source code references are welcome.
2. _syscall4
After reading http://www.kegel.com/c10k.html, I have to wonder how exactly sendfile() was implemented in the 2.4.x kernels? Where in the source can I find information? Is there any published documentation on this subject as well?
3. PID table resizing
I understand that it is possible to resize the PID table in the 2.4.x kernels? Is this true or misinformation? If true, what do I need to do? Is this a source edit, a compile-time configuration option or a runtime option? If a source edit, which file(s)?
Thanks in advance!
