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! //////////////////////////////////////////////////////////////////// Khyron mailto:[EMAIL PROTECTED] Key fingerprint = 53BB 08CA 6A4B 8AF8 DF9B 7E71 2D20 AD30 6684 E82D "Drama free in 2001!" \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
