From c34e333fd5ca41317c3dab69ed8a212acacd4aeb Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 3 Sep 2013 09:46:45 +0900 Subject: 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.
