[PATCH 0/3] regression fixes for 2.6.29

[Christoph Hellwig]

These are the patches that fix regressions and should go into 2.6.29 ASAP.
The thid patch is also a candidate for 2.6.28-stable.

All the other patches I sent to the list over the previous week are also
small and useful enough fixes that I think they should still go into 2.6.29,
but it's not as urgent.  I'll prepare another series for those over the
weekend.
