1.6.x stable series
===================

NOTE:

A discussion was held on what the requirements are for merging commits on the
stable branch. Gerrits require +1 to be merged at a minimum. Gerrits changing
difficult areas, such as ubik, require multiple +1s from developers familiar
with that area of the code, even after being merged on the master branch.
Reviewers should note if the changes are back-ported correctly and are
appropriate for the stable branch.

Other candidates, backported from 1.8.x/master. Reviews for 1.6.x branch are
needed.

1.8.x series
============

1.8.0pre4 (beta) is available.  Test reports would be appreciated.
Some positive responses on irc (#openafs on freenode.net)

Andrew submitted a change for a deadlock in master/1.8 on old
kernels that have the splice alias race. May be needed for 1.8.0.

12868  LINUX: Avoid locking inode in check_dentry_race


master
======

The autoconf refactoring changes were merged on master recently.

Andrew did raised a question of a possible memory leak in the rxgk crypto code
if krb5_init_context could sporadically fail. Ben as come around to the
position of embedding a krb5_context in the rxgk_key structure as the least-bad
option for now.

Ubik fixes. We need to know if these changes are required
for stable after the set of 12803,12806,12807,12811,12814

12716   ubik: update ubik_dbVersion during SDISK_SendFile
12640   ubik: check if epoch is sane before db relabel
