Comment 20 for bug 692848

Added backports for Lucid, Karmic and Hardy to be included for the next proposed cycle. It was decided to skip Dapper. First I could not see that problem there (there were rather other problem which I could not really claim to be a regression as its not clear how well xfs worked back then). Also the additional patch notes that performance should be ok with the radix based inode tree. That was not there before Hardy. So better leave things alone unless someone has real issues.
