### f2fs mount options, taken from wiki:
# compress_algorithm=zstd:6 tells F2FS to use zstd for compression at level 6, which should give pretty good compression ratio.
# compress_chksum tells the filesystem to verify compressed blocks with a checksum (to avoid corruption)
# whint_mode=fs-based[7] Try to optimize fs-log management depending on file "hotness", meaning how often this data will be read/written to.
# atgc,gc_merge Enable better garbage collector, and enable some foreground garbage collections to be asynchronous.
# lazytime Do not synchronously update access or modification times. Improves IO performance and flash durability.
