Hi thanks for this. I suppose you are referring to the commit: http://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=b47231be6813e6cb5305266e391b4bb745f27f13 >From http://git.savannah.gnu.org/cgit/coreutils.git/log/?qt=grep&q=mv%3A, http://git.savannah.gnu.org/cgit/coreutils.git/plain/NEWS?id=b47231be6813e6cb5305266e391b4bb745f27f13 and finally http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/mv.c?id=b47231be6813e6cb5305266e391b4bb745f27f13 it doesn't seem as if there was any earlier commit actually adding a --reflink option so it seems the improvement is in-built. That's nice to know! Any idea when the next coreutils point release with this will be out? -- Shriramana Sharma ஶ்ரீரமணஶர்மா श्रीरमणशर्मा -- 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
