Kernel release status

The current development kernel is 2.5.58. Linus seemingly made a New Year's resolution to release kernels more often, with the result that four separate releases came out over the last week:

  • 2.5.58 (announcement, changelog) featured a lot of relatively small, janitorial fixes, along with the IPMI driver, a USB update, some changes to the new generic DMA layer, the "red/black tree" I/O scheduler, more sysfs work, and an RPCSEC_GSS implementation (needed for NFSv4).

  • 2.5.57 (announcement, changelog) had fixes for the information leakage bug in a number of network drivers, a few IDE changes, the low-latency page table teardown patch (covered in last week's LWN Kernel Page), an ISDN update, and a bunch of driver model/sysfs work.

  • 2.5.56 (announcement, changelog) had a bunch of netfilter work, some USB updates, an ACPI update, and a forward port of the 2.4 watchdog driver code.

  • 2.5.55 (announcement, changelog) came with with a number of big architecture updates (PowerPC, ARM, x86-64), some kbuild work, a knfsd update, more module fixes, another set of driver model patches, some device mapper updates, and a number of video4linux tweaks.

Linus's BitKeeper tree, which will likely become 2.5.59 fairly soon, contains some uClinux patches, an XFS update, and some new algorithms for the crypto API.

Note that new development kernel releases will come to a halt by Friday, when Linus takes off for a two-week vacation.

The current stable kernel is still 2.4.20; Marcelo has released no 2.4.21 prepatches over the last week.

The latest patch from Alan Cox is 2.4.21-pre3-ac4, which resumes work on the IDE layer.
