From 14cecc5cd6ed33ef3cb7328de904cc636dd390a4 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Mon, 15 Sep 2014 18:03:32 +0800 Subject: f2fs: skip punching hole in special condition Now punching hole in directory is not supported in f2fs, so let's limit file type in punch_hole(). In addition, in punch_hole if offset is exceed file size, we should skip punching hole.
