2.6.27-rc8, "This One Should Be The Last One"
"So yet another week, another -rc," began Linux creator, Linus Torvalds, announcing the 2.6.27-rc8 Linux kernel. He continued, "this one should be the last one: we're certainly not running out of regressions, but at the same time, at some point I just have to pick some point, and on the whole the regressions don't look _too_ scary. And -rc8 obviously does fix more of them." Linus went on to n...
2.6.27-rc6, "Things Are Calming Down"
"The patches most people hopefully care about tend to be small details," noted Linus Torvalds, announcing the 2.6.27-rc6 kernel. He continued, "and so more regressions should hopefully be closed now, some by just reverting the commits that caused breakage. I don't think anything special merits explicit comment, but you can get a flavor for things by scanning the appended shortlog." Earlier i...
Tux3 Acting Like A Filesystem
Daniel Phillips noted that his new Tux3 versioning filesystem is now operating like a filesystem, "the last burst of checkins has brought Tux3 to the point where it undeniably acts like a filesystem: one can write files, go away, come back later and read those files by name. We can see some of the hoped for attractiveness starting to emerge: Tux3 clearly does scale from the very small to the v...
2.6.27-rc5, Fixing Regressions
Linus Torvalds announced the 2.6.27-rc5 Linux Kernel, noting that his "weekly releases" tend to happen every eight days, adding, "the bulk of it is all config updates, and with arm and powerpc leading the pack." Linus continued:
"While the config updates amount to about three quarters of the diff, and if you don't use a rename-aware diff the blackfin include file movement pretty much accounts ...
2.6.27-rc4, "Random Stuff All Over"
"Another week, another -rc," began Linus Torvalds, announcing the 2.6.27-rc4 Linux kernel, continuing, "this time the diffstat is almost totally dominated by the addition of the musb driver that drives the MUSB and TUSB controllers integrated into omap2430 and davinci. That, together with the removal of the auerswald USB driver (replaced by libusb version) is more than half of the bulk of the p...
AXFS, Advanced Execute In Place Filesystem
"I'd like to get a first round of review on my AXFS filesystem," began Jared Hulbert, describing his new Advanced XIP File System for Linux. XIP stands for eXecute-In-Place. The new filesystem received quite a bit of positive feedback. Jared offered the following description:
"This is a simple read only compressed filesystem like Squashfs and cramfs. AXFS is special because it also allows f...
Git 1.6.0 Released
"The latest feature release GIT 1.6.0 is available at the usual places," began Git maintainer, Junio Hamano, announcing the latest stable release of the distributed version control system originally written by Linus Torvalds. Among the current changes, Junio noted, "with the default Makefile settings, most of the programs are now installed outside your $PATH, except for 'git', 'gitk' and some ...
64-bit Application Thread Creation Performance
A recent discussion on the Linux Kernel mailing list noted that threaded 64-bit applications suffer a drastic slowdown in pthread_create performance when stack utilization goes above 4GB. Ingo Molnar offered an explanation of the problem, "unfortunately MAP_32BIT use in 64-bit apps for stacks was apparently created without foresight about what would happen in the MM when thread stacks exhaust ...
Tux3 Hierarchical Structure
"It is about time to take a step back and describe what I have been implementing," began Daniel Phillips, referring to his new Tux3 filesystem. He provided a simple ASCII diagram that detailed the filesystem's hierarchical structure, describing each of the elements. About one he noted, "the volume table is a new addition not central to the goals of Tux3, but a nice feature to have given that ...
2.6.27-rc3, "Things Really _Have_ Calmed Down"
"Things really _have_ calmed down, and hopefully we've also resolved a lot of the regressions in -rc3," began Linus Torvalds, announcing the 2.6.27-rc3 Linux kernel. He noted that much of the patch size was from the inclusion of the new ath9k wireless driver, with much of the rest of the patch size due to the renaming of many arch include files in the ARM, AVR32 and m68lnommu architectures. ...
