I realised that we'd get a messy, messy conflict if I separated the
per-ag tree reclaim tracking from the shrinker patchset, so I
included it in that one as it was also part of fixing reported
XFS shrinker regressions to avoid such conflicts.
But yes, i think that all the lockdep fixes are probably 2.6.35
material.
Cheers,
Dave.
