Yes please! It's hard to come with a good reason for not reflinking when it's possible -- the only one I see is if you have a nocow VM and want to slightly improve speed at a cost of lots of disk space. And even then, there's cat a >b for that. And the cost on non-btrfs non-unmerged-xfs is a single syscall per file, that's utterly negligible compared to actually copying the data. -- An imaginary friend squared is a real enemy. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
