Javier González d672d92d9c lightnvm: pblk: guarantee mw_cunits on read buffer ... OCSSD 2.0 defines the amount of data that the host must buffer per chunk to guarantee reads through the geometry field mw_cunits. This value is the base that pblk uses to determine the size of its read buffer. Currently, this size is set to be the closes power-of-2 to mw_cunits times the number of parallel units available to the pblk instance for each open line (currently one). When an entry (4KB) is put in the buffer, the L2P table points to it. As the buffer wraps up, the L2P is updated to point to addresses on the device, thus guaranteeing mw_cunits at a chunk level. However, given that pblk cannot write to the device under ws_min (normally ws_opt), there might be a window in which the buffer starts wrapping up and updating L2P entries before the mw_cunits value in a chunk has been surpassed. In order not to violate the mw_cunits constrain in this case, account for ws_opt on the read buffer creation.
