This patch improves the gc efficiency by optimizing the victim
selection policy. With this optimization, the random re-write
performance could increase up to 20%.
For f2fs, when disk is in shortage of free spaces, gc will selects
dirty segments and moves valid blocks around for maki
Yes, I will submit the patch later.

It seems that we can obtain the performance gain just by setting the

So, how about just adding an ending criteria like below?
I agree that we could get the performance improvement by

For f2fs, foreground gc happens when disk is lack of free spaces,
it selects dirty segments and moves valid b
