From ae1519ec448bc31a7fe7369b66e7c78872f91e84 Mon Sep 17 00:00:00 2001 From: Matias Bjørling Date: Wed, 28 Oct 2015 19:54:57 +0100 Subject: rrpc: Round-robin sector target with cost-based gc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This target allows an Open-Channel SSD to be exposed asas a block device. It implements a round-robin approach for sector allocation, together with a greedy cost-based garbage collector.
