Javier González 7bd4d370db lightnvm: pblk: guarantee line integrity on reads ... When a line is recycled during garbage collection, reads can still be issued to the line. If the line is freed in the middle of this process, data corruption might occur. This patch guarantees that lines are not freed in the middle of reads that target them (lines). Specifically, we use the existing line reference to decide when a line is eligible for being freed after the recycle process.
