From b08b12d2ddc85b977a0531470cf6a7158289aaaf Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 18 Nov 2016 22:27:41 +0800 Subject: f2fs: fix incorrect free inode count in ->statfs While calculating inode count that we can create at most in the left space, we should consider space which data/node blocks occupied, since we create data/node mixly in main area. So fix the wrong calculation in ->statfs.
