Javier González	d7a64d275b	lightnvm: reference rrpc lun in rrpc block ... Currently, a rrpc block only points to its nvm_lun. If a user wants to find the associated rrpc lun, it will have to calculate the index and look it up manually. By referencing the rrpc lun directly, this step can be omitted, at the cost of a larger memory footprint. This is important for upcoming patches that implement write buffering in rrpc.

Matias Bjørling	b7ceb7d500	lightnvm: refactor phys addrs type to u64 ... For cases where CONFIG_LBDAF is not set. The struct ppa_addr exceeds its type on 32 bit architectures. ppa_addr requires a 64bit integer to hold the generic ppa format. We therefore refactor it to u64 and replaces the sector_t usages with u64 for physical addresses.

Matias Bjørling	ae1519ec44	rrpc: Round-robin sector target with cost-based gc ... 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.
