From f56aa1c57ea921e45bb6cf5d83a04cbc8f38fae5 Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Tue, 2 Jun 2015 15:48:20 -0700 Subject: f2fs: fix to return exact trimmed size Now, we add all the candidates for trim commands and then finally issue discard commands. So, we should count the trimmed size in back-end.
