Linux: 2.6.16 Kernel Released

Submitted by Jeremy
on March 20, 2006 - 3:09pm

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.

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

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.

2.2.x, 2.4.x & early 2.6.x were taking very very long time to do that, also more or less locking up system completely.

real    1m23.764s

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:

$ time dd if=/dev/zero of=tmp00 count=512 bs=1048576
512+0 records in
512+0 records out

real    0m24.129s
user    0m0.010s
sys     0m5.050s
$ sync
$ time cp ./tmp00 ./tmp01

real    1m13.585s
user    0m0.130s
sys     0m9.440s

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...

$ time dd if=/dev/zero of=tmp00 count=64 bs=1048576
64+0 records in
64+0 records out

real    0m21.772s
user    0m0.020s

$ sync
$ time cp ./tmp00 ./tmp01

real    0m47.830s
user    0m0.620s
sys     0m37.940s

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."

$ RAM="put here amount of ram you have in megabytes"
$ dd if=/dev/zero of=./tmp01 count=$[2*$RAM] bs=$[1024*1024]

With GNU dd you can use suffixes like M for megabytes:
$ dd if=/dev/zero of=./tmp01 count=$[2*$RAM] bs=1M

this is little test for the behaviour of page cache. on *BSD it take some time

It would be nice if you had provided some results from these BSDs then.

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

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?
