That's good, I saw info I need
And I also found a f2fs-tools which contains dump.f2fs
dump.f2fs -a will dump SSA info.
How to read the SSA entry info from the dumped file named dump_ssa?
It looks like:
segno: 0, Current Node
[0: d93][1: d95]...etc
[10: da2]...etc
...etc
Take [0: d93] for example, 0 means the first segment and d93 means what?
