Hi all, Is there anybody know how to invoke the "discard" operation over btrfs filesystem? Does delete a file by "rm" will trigger the "discard" operation? If I want to trigger "discard" operation,how should i do? if there any pre-requires? such as the device must be ssd, btrfs should be mounted with "-o discard". Any suggestion is appreciated. Thanks a lot! -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
