Availability of unsupported kernel for 4.2 or compiling reiser into 4.2 kernel

[lists at starground.it (Dave Hatton)]

Two related questions.

1. When is the unsupported version of 2.6.9.22 likely to be available? 
?? I need to access reiser filesystems so I?m currently running on the
.11unsupported kernel.

2. Has anyone successfully compiled reiser into the 2.6.9.22 kernel? 
???I am getting errors in stree.c but I can?t find a solution on the net?

Thanks
