I couldn't find any special constraint with the large section
after I read GC and SSR selection flow... :(
And since now f2fs has aggressive SSR, different types of node
or different types of data will be mixed in a segment...
I have turned to Yun Lei and Yong for help, but we still cannot
get any conclusion on it.
Could you give me some hints on the large section?
Thanks again
