Hi all, This adds an iteration function to the perag iteration macros to tweak the logic and avoid some raciness with growfs when relying on the presence of xfs_perag structures. This manifests as a couple assert failures reproduced by xfs/104 (which only seem to reproduce on ppc64le at the moment; I haven't really dug into why). This probably could use a couple more patches tacked on: one to fix up the tag based lookup macro and another to audit the existing callers and remove any spurious xfs_perag_put() calls. I don't think the former is currently an issue an practice, but we should probably eliminate the flaw regardless. I'm just sending the initial fixup on its own as a first pass..
