Too many people have ideas for SSD-as-cache in L= inux, in non particular order: =E2=80=94 bcache =E2=80=94 cleancache=20 =E2=80=94 btrfs temperature tracking =E2=80=94 dm-hstore =E2=80=94 dm-cache / flashcache Patches are in various states of implementation, some with explicit b= trfs support. There's no clear winner at this time, but some of above solut= ions are shipped in distro kernels. --=20 Tomasz Torcz "God, root, what's the difference?" xmpp: zdzichubg@chrome.pl "God is more forgiving." -- 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
