Kernel release status

The current 2.6 prepatch is 2.6.21-rc3, released by Linus on March 6. It contains quite a few fixes and some KVM enhancements. Says Linus: "...there's some hope that it will work more widely than -rc1 and -rc2 did." The long-form changelog has the details.

As of this writing, no patches have been merged into the mainline git repository since -rc3 was released.

The current -mm tree is 2.6.21-rc2-mm2. Recent changes to -mm include a set of memory anti-fragmentation patches (see below), the dropping of the buffered filesystem I/O patches, the Devicescape wireless stack (now rebranded "mac80211"), and a new krealloc() memory allocation function.

For older kernels: 2.6.19.6 and 2.6.19.7 were released on March 2. They contain a fair number of fixes, at least one of which is security-related. "Barring anything major, there will not be any more 2.6.19 releases. If you disagree with this, please let the stable team know about the patches that you feel must be in a new release. We need to move on to flushing out the very large backlog of 2.6.20-stable patches."

2.6.16.43-rc1 was released on March 1. It contains a fair number of fixes and a few new hwmon drivers.
