Where is the Centos Linux 5.5 kernel syscall handler for mmap? (Keith Roberts)
Keith Roberts, Thank you for your suggestion about doing a grep of the source code. We found mmap.S in ../sysdeps/unix/sysv/linux/i386. We looked in mmap.S and found a lot of assembly code. Could you please tell us if any of the assembly code call the kernel syscall handler for mmap.s?
Also, we ran make for the kernel Makefile and we obtained the following result shown below. Could you please

status of autotuning freebsd for 9.2
Andre,
Are you going to have time to MFC things from -current for auto-tuning
-stable before 9.2?
I fear (maybe unnecessarily?) that we are about to ship yet another

If you don't have time, then let me know and I'll see what I can do.
