Abstract
A system comprising a processor and a memory storing instructions that, when executed, cause the system to receive a request for garbage collection, identify a range of physical blocks in a storage device, query a bitmap, the bitmap having a bit for each physical block in the range of physical blocks, determine a status associated with a first bit from the bitmap, in response to determining the status associated with the first bit is a first state, add a first physical block associated with the first bit to a list of physical blocks for relocation, and relocate the list of physical blocks.
