I don't know anything about GFS, but expecting a filesystem author to use a journaling layer he does not want to is a bit arrogant. Now, if you got into details, and said jbd does X, Y and Z, and GFS does the same X and Y, and does not do Z as well as jbd, that would be a more serious comment. He might want to look at how reiser4 does wandering logs instead of using jbd..... but I would never claim that for sure some other author should be expected to use it..... and something like changing one's journaling system is not something to do just before a merge..... >Now the question for GFS is still a valid one; there might be reasons to >not use it (which is fair enough) but if there's no real reason then >using jdb sounds a lot better given it's maturity (and it is used by 2 >filesystems in -mm already). > > > >- >To unsubscribe from this list: send the line "unsubscribe linux-kernel" in >the body of a message to majordomo@vger.kernel.org >More majordomo info at http://vger.kernel.org/majordomo-info.html >Please read the FAQ at http://www.tux.org/lkml/ > > > >
