linux26-9p RC1 Released

Big changes are mostly around reworking how we handle file_info, FIDs, and when we clunk. I also fixed a handfull of bugs as I came across them. I'm not entirely happy with the code at this point, but it is functional. My plan is to do another pass to clean things up (including finally getting around to rewriting the Rerror mapping code), incorporate any changes from the v9fs-developers community, and call that RC2, which I will then release to LKML.

Please review the code, try it out on your systems, and send any and all feedback.
