F2fs do_garbage_collect
WebF2FS is a file system exploiting NAND flash memory-based storage devices, which is based on Log-structured File System (LFS). The design has been focused on addressing the fundamental issues in LFS, which are snowball effect of wandering tree and high cleaning overhead. Since a NAND flash memory-based storage device shows different characteristic Compared with the traditional log-structured file system, F2FS has some improvements and optimizations to address the problems such as the high time overhead of the wandering tree and garbage collection. You can refer to the F2FS paper with this link.
