SWAT command and API for atomic swap and trim of LBAs

摘要

Exemplary embodiments provide access to an updated file performed by at least one processor, wherein responsive to receiving a first list of logical block addresses (LBAs) and a second list of LBAs for an update, wherein the first list of LBAs is mapped to a first list of physical block addresses (PBAs), and the second list of LBAs is mapped to a second list of PBAs, the method, comprising: atomically remapping the first list of LBAs so that the first list of LBAs is mapped to the second list of PBAs; trimming a mapping of the first list of LBAs to the first list of PBAs; and unmapping the mapping of the second list of LBAs to the second list of PBAs.
