hesela.devNVMe reclaim unit
An FDP storage abstraction within a reclaim group that the controller can physically erase independently of other reclaim units.
A reclaim group contains reclaim units; an RU is not a host logical-address interval or a ZNS zone. [1] In NVM Command Set 1.1, RUAMW reports the currently writable logical-block count. After conversion using the namespace's formatted LBA size, the amount may be smaller or larger than the Reclaim Unit Nominal Size. [2]
