From c08a690b46919e6b531c1a2bb74389323e5f5b1c Mon Sep 17 00:00:00 2001 From: Jaegeuk Kim Date: Wed, 15 Oct 2014 10:16:54 -0700 Subject: [PATCH] f2fs: should truncate any allocated block for inline_data write When trying to write inline_data, we should truncate any data block allocated and pointed by the inode block. We should consider the data index is not 0.
