Kernel Log: Linux 3.2 main development phase complete
Last night, two weeks after releasing Linux kernel 3.1, Linus Torvalds published the first release candidate for Linux 3.2, which he has dubbed Sabre-Toothed Squirrel. This should mean that all of the major changes for kernel 3.2 have now been merged. Between now and the release of the final version, scheduled for late December or early January, the focus for kernel developers will be on bug fixes.
Among the features added by kernel developers is support for the architecture of Qualcom's Hexagon processors. The TCP stack in Linux 3.2 will contain the "proportional rate reduction" algorithm, which has been added by a Google developer and which should enable network connections to be restored faster following temporary data transfer problems. This should speed up data transfer. The CFS process scheduler is now able to limit the CPU time of process groups to prevent users using more than their allocated CPU resources even when unused CPU resources are available.
