It''s planned, but nobody''s got around to implementing it.

I worked on those together with Arne Jansen who sent patches in January 2011, subject "[PATCH] Btrfs: introducing speed profiles and dedicated log devices". I don''t assume they apply nowadays without a major rework, though. We should get those patches merged sometime. -Jan -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
