Kernel release status
The current 2.6 prepatch remains 2.6.20-rc5. Patches have started
flowing into the mainline git repository again, however - 250 or so of
them. These patches are mostly fixes, but there is also a set of patches
from the memory technology devices tree adding an AT91 NAND driver and the
"Cafe" NAND driver (for OLPC systems).
For older kernels: 2.6.16.38 was released on
January 21; it includes fixes for several security problems.
