f2fs: trigger GC when there are prefree segments
Previously, f2fs conducts SSR when free_sections() < overprovision_sections. But, even though there are a lot of prefree segments, it can consider SSR only. So, let's consider the number of prefree segments too for triggering SSR. Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com>
