Gareth Rees 1d9afa915f Fix arenadescribetracts: ... * Return value from TreeVisitor is Bool, not Res, so pass Res back via a closure. * Can't use TRACT_TRACT_FOR while iterating over the chunk tree, because that macro uses ChunkOfAddr. (A plain loop is simpler.) * Mustn't try to describe unallocated tracts -- they might not even be mapped into memory. So consult the allocTable. Make tract functions more robust: * TractCheck must only check the pool if there is one (otherwise it segfaults for unallocated tracts) * TractLimit can't look up the arena via TractPool, because the tract might not have a pool. So pass in the arena as an argument. Copied from Perforce Change: 186547 ServerID: perforce.ravenbrook.com		2014-06-12 18:46:49 +01:00
