I don't know when it will be merged, but I can comment on the status of 
our patches.

Ksplice has essentially two prerequisite changes:

- Changes to the module subsystem.  Rusty Russell included versions of 
those patches in a recent patch series for the module system targeted at 
2.6.30.

- Support for building the Linux kernel with -ffunction-sections 
-fdata-sections.  Linus was asked about a week ago whether he would take 
the patch, but he has not responded yet.

As for the Ksplice core, Rusty Russell has started reading the code and 
has requested some changes to it to assist further review.  We hope to 
send a new patch series with those changes made next week.
