Linux 2.6.30 Kernel Benchmarks
,----[ Quote ]
| With the Linux 2.6.30 kernel being prepped for release in early June, we have
| set out to provide a few benchmarks of this latest Linux kernel to see how it
| compares to its two earlier predecessors. While this new kernel may offer
| support for new file-systems (NILFS2, in particular), support for LZMA/BZIP2
| kernel image compression, a new CPU architecture (Microblaze) and many other
| changes, are there any major performance regressions or improvements like we
| have spotted with our previous Linux kernel benchmarks?
|
| [...]
|
| While this round of kernel testing was brief with just three kernels and
| eleven tests, it does seem that particularly when it comes to disk operations
| there are improvements with the Linux 2.6.30 kernel, which should not come as
| a surprise. There were also a few performance regressions, however. Beyond
| that the tests show few other changes with this kernel upgrade. If you would
| like to run your own Linux kernel benchmarks, try out the Phoronix Test
| Suite, which is our open-source software that will allow you to run and
| automate almost any test on Linux, OpenSolaris, *BSD, and Mac OS X operating
| systems.

Walsh: Introducing the SELinux Sandbox
,----[ Quote ]
| Dan Walsh and Eric Paris have been working on an SELinux "sandbox" which
| Walsh describes on his weblog. The basic idea is to use SELinux to restrict
| the kinds of actions a user application can perform. This would allow users
| to run untrusted programs or handle untrusted input in a more secure manner.

Linux 2.6.30-rc7
,----[ Quote ]
| Ok, so 90% of the patch is the addition of one new driver, at around 9000
| lines for the the Cisco PCI-Express FCoE HBA SCSI driver.
|
| If you ignore that (and you should - unless you happen to have such hardware
| and have been pining for the driver to be merged for a long time), the rest
| is really mostly a collection of small fixes. Several regressions fixed,
| lots of small cleanup.

Linux 2.6.30-rc6
,----[ Quote ]
| Things definitely are calming down, with just about 300 commits in the last
| week. And most of them are pretty small too, although the powerpc updates
| brought some defconfig changes that look largish.

Linux 2.6.30-rc5
,----[ Quote ]
| It's been a week (and a couple of days - what can I say?), so here's a
| new -rc.
|
| It's been getting quieter, although by -rc5 I obviously always hope for not
| just "pretty quiet" but "almost deathly quiet", and it never is.

Kernel Log: What's coming in 2.6.30 - File systems: New and revamped file
systems
,----[ Quote ]
| The patches adopted in Linux 2.6.30 introduce many significant changes
| affecting data security and Ext3 and Ext4 performance. Support for the EXOFS
| and NILFS2 file systems is new, as is the cache for the AFS and NFS network
| file systems. There are also a few fixes for the almost forgotten ReiserFS
| file system.

Exciting changes in the 2.6.30 Linux kernel
,----[ Quote ]
| Every Linux kernel release has interesting changes but 2.6.30 really stands
| out to me as having a lot of features I would like to take advantage. In
| 2.6.29 the only really great feature to me was the inclusion of barrier
| support for simple DM devices. It’s only 1 change but an important one in my
| opinion as it will allow an increase in either performance or reliability for
| LVM and dm-crypt devices. But 2.6.30 has a lot of changes that I am likely to
| take advantage of such as:
|
| * The addition of nilfs - I’ve tested nilfs and I am happy to see it
| adopted. I’ve run into problems using it but would like to see it become
| stable. It seems likely to beat btrfs as the first stable Linux disk
| filesystem with snapshots.

Ext3 ‘data=guarded’ mode coming for Linux kernel 2.6.30?
,----[ Quote ]
| There were some patches from Theodore T’so - the Ext4 maintainer, Jens
| Axboe - the block layer maintainer, Chris Mason - the Btrfs developer et al.
| An overview of the discussion can be found at LWN.net, here.

Linux Supports More Filesystems With 2.6.30-rc1
,----[ Quote ]
| Two weeks have passed since the release of the Linux 2.6.29 kernel that
| brought Intel kernel mode-setting, the Btrfs file-system, and many other
| improvements to the Linux kernel. Now though the first release candidate for
| the forthcoming Linux 2.6.30 kernel is now out in the wild.

Kernel Log: Development of 2.6.30 is under way
,----[ Quote ]
| Shortly after the release of Linux 2.6.29 last Tuesday, the kernel subsystem
| developers began to prepare the first changes to be merged into the main
| development branch for Linux 2.6.30. This is usually done by sending a "Git
| pull request" – an email which includes the URL to a Git tree with the
| proposed changes as well as a diffstat and a list of individual patches – not
| only to Linus Torvalds, but usually also to the LKML (Linux Kernel Mailing
| List). Often, the maintainer of the subsystem starts the email with a short
| summary of the proposed changes, highlighting the most important ones, or
| putting the changes into context.

Kernel Log: What's coming in 2.6.30 - Storage: RAID improvements, optimised CFQ
Scheduler, SAS drivers
,----[ Quote ]
| The next kernel version is to provide all that's necessary to convert, for
| example, a RAID 5 into a RAID 6 and vice versa. There are changes to the
| block layer designed to speed up the system, and new and improved drivers
| will offer better SAS support.
|
| With the fifth release candidate of Linux 2.6.30 out a few days ago, the
| development of the next kernel version in the main development line continues
| to progress. As indicated by Linus Torvalds in his release email, the changes
| are slowly decreasing in number and size, which is what usually happens at
| this development stage.
