Linus Torvalds announced the release of the 2.6.16 Linux kernel. He noted, "not a lot of changes since -rc6, but there's various random one-liners here and there (a number of Coverity bugs found, for example), and there are small MIPS and PowerPC updates." You can download the latest kernel from your nearest Linux Kernel Archive mirror [story], and browse through all the changes using the 2.6 kernel's gitweb interface.

Subject: Linux v2.6.16
Date: Sun, 19 Mar 2006 22:23:04 -0800 (PST)
Ok, it's being mirrored out right now, the git tree should already be all
there, the tar-file and patches are still uploading.
Not a lot of changes since -rc6, but there's various random one-liners
here and there (a number of Coverity bugs found, for example), and there
are small MIPS and PowerPC updates.
Appended is the shortlog from 2.6.16-rc6, the full log (from 2.6.15) is on
the web/ftp-sites.
It looks like both Fedora and SuSE end up using a kernel that is pretty
close to this 2.6.16 release, so let's all hope it's good. Give it a good
testing, please,
Linus

Can anyone with vanila kernel perform little test for me?
$ RAM="put here amount of ram you have in megabytes"
$ dd if=/dev/zero of=./tmp01 count=$[2*$RAM] bs=$[1024*1024]
$ sync
$ time cp ./tmp01 ./tmp02
this is little test for the behaviour of page cache. on *BSD it take some time. on wind0ze it is somewhat slower. on normal linux the test takes *ages* and make system unusable when cp reaches the middle of the test file.
P.S. the test presumes that you do not have sparse files forced on file system.

cp, is that the same source code in bsd as in linux?

ext3
Tried this on my 2.6.10 Ubuntu box.
I ran this on my Ubuntu 5.4 system with Ubuntu's stock 2.6.10 kernel. I have 1GB RAM, a single Opteron 246 (for now), and a 3x300GB SATA software RAID-5 setup with an ext3 filesystem. Judging by "vmstat 1" output, the copy was very well behaved and didn't force anything into swap. Machine felt responsive the whole time. I didn't even notice this copy was running.
For fun, I also ran it on an old RedHat 7.3 machine, with the RH's stock 2.4.18 kernel. That machine is a 1.2GHz Duron with 256MB RAM and an aging 20G IDE drive. Here's how it fared:
Again, vmstat showed pretty tame VM performance, with nothing being pushed to swap. Interactively, the computer felt *slightly* laggy initially when logging in over an ssh connection, but nothing too major.
I grabbed Mr. Peabody and hopped in the Wayback Machine, and ran this same test on my Pentium-60 (yes, sixty, not six hundred) running RH 7.3, Linux 2.4.18, 32MB RAM and a 1GB ancient hard drive...
I don't have any 2.2 kernel based machines to try, but I think I have to call shenanigans on "All of 2.4 sucked."

System was a bit loaded during test.
Compare with... what?
With GNU dd you can use suffixes like M for megabytes:
$ dd if=/dev/zero of=./tmp01 count=$[2*$RAM] bs=1M
It would be nice if you had provided some results from these BSDs then.
fxxk the test
I think this is not the test of the page cache,but the test of the filesystem's ,disk's and the inod allocateing speed.
The bsd use ufs soft update only merge the inod later,so time cp means nothing for bsd.
I think the bsd test using the cheating data,because it costed only 0.008s in the sys and only 2% 's cpu,but the linux cost 0.8s and 50%'s cpu.while the former yet took longer time waiting experience than linux
the default ext3 sync the journal every 5s , so this test is a butt
2.6.16.x will be a long-living kernel series
This is great news from Adrian Bunk. I hope the kernel will gain more stability by maintaining it longer. If this succeeds, I will certainly have my servers on his tree.

Using 2.6.15.6 config file I have no iptables. I look in /lib/modules/2.6.16/kernel/net/ipv4/netfilter and I seem to be missing a lot of modules. I always use my old config file to make my kernels and never have this problem. I also use a script so I know I did the same thing I do every other time.
Is there a reason my old 2.6.15.6 config file doesn't work with this new kernel?
Well I just had to turn on a
Well I just had to turn on a bunch of iptables stuff. Don't know why the settings didn't transfer from my old config file:

If I comment this out then it works. Why do I have to do this with kernel-2.6.16?
