Linux 2.6.30's best five features 

,----[ Quote ]
| 1. Fast boot. Older versions of Linux spend a lot of time scanning for hard 
| drives and other storage devices and then partitions on each of them. This 
| eats up a lot of milliseconds because it looks for them one at a time. With 
| the 2.6.30 boot-up, however, instead of waiting for this to get done the rest 
| of the kernel continues to boot-up. At the same time, the storage devices are 
| being checked in parallel, two or more at a time, to further improve the 
| system's boot speed.      
| 
| There are other efforts afoot to speed up Linux's boot times. The upshot of 
| all this work will be to keep Linux the fastest booting operating system well 
| into the future.

A Visual Expedition Inside the Linux File Systems

,----[ Quote ]
| This is an attempt to visualize the relationships among the Linux File 
| Systems through the lens of the external symbols their kernel modules use. We 
| took an initial look a few months back but this time the scope is much 
| broader. This analysis was done on 1377 kernel modules from 2.6.0 to 2.6.29, 
| but there is also a small dip into the BSD world.

Linux 2.6.30 gets new filesystems

,----[ Quote ]
| The new NILFS2 treats the whole disk as a consecutive list of blocks
| (or "log"), and never rewrites blocks. As a result, all modifications and
| creations are converted into sequential operations, which are said to be
| faster. Other NILFS2 improvements are said to include the ability to offer a
| more coherent historical view of operations, called "continuus snapshotting,"
| enabling users to restore files that have been mistakenly destroyed only a
| few seconds previously.

Torvalds proclaims 'new world order' with Linux 2.6.30

,----[ Quote ]
| Linux kernel 2.6.30 has been released with hundreds of changes from the
| previous version, including a new architecture for suspend and resume which
| Linus Torvalds says switches the kernel to a "new world order".

2.6.30 Kernel and Sidux

,----[ Quote ]
| Sidux Linux, based on Debian Sid (the 'unstable' branch) and touted as
| being 'Debian Hot & Spicy!', has released their 2.6.30 kernel with a huge
| surprise.
|
| If you read around the web about the release of this new kernel, nearly every
| article discusses increased performance and a large number of new drivers for
| the 2.6.30 kernel release. But within Sidux, the kernel developer slh has
| decided to remove all non-Free (Libre) firmware from the Sidux kernels. The
| result is poor hardware performance within Sidux 2.6.30 kernels, at least
| thus far according to rants on the OFTC irc network on the #sidux and #smxi
| channels.

Linux 2.6.30 Gets Faster Boot

,----[ Quote ]
| The second Linux kernel of 2009 is now out, sporting a long list of
| improvements -- and at least one regression.
|
| New filesystem support, security and driver improvements are all part of the
| new Linux 2.6.30 kernel release, although one of the most noticeable elements
| in the new release is the kernel inclusion of fastboot, an enhancement
| designed to speed startup for Linux-based systems.

Linux Kernel 2.6.30 released

,----[ Quote ]
| After eight release candidates and a rather short development cycle, Linus
| Torvalds has released Linux version 2.6.30, dubbed "Man-Eating Seals of
| Antiquity". As with its predecessors on the main development line of Linux,
| it introduces a host of innovations.

Fine tuning

,----[ Quote ]
| Although it wasn't explicitly planned this way, a whole lot of the changes
| made in the new kernel version have an impact on file systems and data
| storage. There are, however, also plenty of changes elsewhere, for example
| faster booting, more efficient compression algorithms and hundreds of new and
| improved drivers.

Kernel Log: What's coming in 2.6.30 - Architecture and infrastructure

,----[ Quote ]
| Linux 2.6.30 can be compressed using Bzip2 and LZMA, includes security
| framework Tomoyo and should boot faster. Tasmanian devil Tuz, who stood in
| for Tux as Linux mascot in 2.6.29, has been relieved of his duties.

USB hardware, netbooks and notebooks

,----[ Quote ]
| The kernel developers have added new features to thousands of the Linux
| kernel's existing drivers and integrated numerous additional drivers. This
| further increases the variety of hardware supported by Linux.
|
| A few days ago, Linus Torvalds released the seventh Linux 2.6.30 release
| candidate. According to Torvalds, most of the merged changes are minor, and
| the next big kernel version is nearing completion – although Torvalds does
| still anticipate an eighth release candidate. The Kernel Log takes this
| opportunity to discuss what's new in the driver arena of Linux 2.6.30; the
| final version of the forthcoming kernel will probably be released in one to
| three weeks.

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.

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.
