Exactly, thats the one and came with 3.10... versions move too fast I ended up mixing up them. http://kernelnewbies.org/Linux_3.10#head-a0ad787f2e030b53bdabbb4b6e22e7ed16803bb1 --- Bcache, a block layer cache for SSD caching Since SSD storage devices became popular, many people has used them to speed up their storage stack. Bcache is an implementation of this functionality, and it allows SSDs to cache other block devices. It's analogous to L2Arc for ZFS, but Bcache also does writeback caching (besides just write through caching), and it's filesystem agnostic. It's designed to be switched on with a minimum of effort, and to work well without configuration on any setup. By default it won't cache sequential IO, just the random reads and writes that SSDs excel at. It's meant to be suitable for desktops, servers, high-end storage arrays, and perhaps even embedded. --- FC -- During times of Universal Deceit, telling the truth becomes a revolutionary act Durante épocas de Engaño Universal, decir la verdad se convierte en un Acto Revolucionario - George Orwell -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
