LOG-STRUCTURED FILE SYSTEM FOR A ZONED BLOCK MEMORY DEVICE
This abstract first appeared for US patent application 20240419636 titled 'LOG-STRUCTURED FILE SYSTEM FOR A ZONED BLOCK MEMORY DEVICE
Original Abstract Submitted
a processing device writes file system data to a first area of a memory zone of a zoned block memory device based on a current position of a write pointer within the memory zone. the file system data comprises data files contained within a file system and file structure metadata describing a file structure of the file system. the processing device detects a write event based on the write pointer advancing past a predetermined memory address within the memory zone that corresponds to a checkpoint. the checkpoint is a second area within the memory zone that is designated for storing write event data. based on detecting the write event, the processing device writes write event data to the checkpoint, the first write event data indicating a most recent memory address of a root node of the file structure within the memory zone.
