Kernel release status [LWN.net]

The current 2.6 prepatch is 2.6.21-rc7, released by Linus on April 15. The list of fixes is relatively short; the next release - expected any day now - should be the final 2.6.21 kernel.

About 30 fixes have been merged into the mainline git repository since -rc7. Also merged is the removal of the unused alloc_skb_from_cache() function.

The current stable 2.6 kernel is 2.6.20.7, released on April 13. It contains fixes for a dozen or so serious problems.

For older kernels: 2.6.16.47 was released on April 14, followed by 2.6.16.48 on April 16. Each contains around a dozen fixes, some of which are security-related.
