I am looking at linux-2.4.18 with 2.4.18-rmap12h. I can't find swap_out_mm() there. So I just changed a bit as following: --- mm/memory.c.bak Fri Jul 12 11:31:00 2002 +++ mm/memory.c Fri Jul 12 11:31:19 2002 @@ -1385,8 +1385,7 @@ * If we are over our RSS limit and the system needs memory, * we will free memory for the non-hogs and slow down a bit. */ - if (mm->rlimit_rss && mm->rss > mm->rlimit_rss && - free_high(ALL_ZONES) > 0) + if (mm->rlimit_rss && mm->rss > mm->rlimit_rss) rss_free_pages(GFP_HIGHUSER); /* But still the RSS limit is not enforced. Where else should I change? or I should refer to another kernel version? BTW, I have tested "setrlimit()" by a simple program, it just behaves the same as "ulimit".
