The -ENOSPC fix is attached, 2.6 should have the same bug (it was
introduced with the new allocator) so I'm porting the fix there. 
Basically after a data block allocation fails, we need to trigger and
wait on a commit so we can reclaim any blocks freed in transactions that
have not yet been comitted.

Well there are a few basic categories:

Major featuers -- data logging, xattrs/acls
Backports of fixes
Support for new generic code - aio, laptop mode, barriers, o_direct
minor performance tweaks

Any significant feature or big performance tweak ends up posted here,
the minor stuff I tend to try out in the suse qa/testing process to see
if it is worth maintaining over the long haul.

The nosrc src kernel rpms (perhaps the worst named thing on the planet)
have the individual patch files.  The suse kernel has quite a few
patches, and most of the changes I don't upload to pub/people/mason are
dependent in some large way on other patches in the suse kernel.
