Hyeong-Jun Kim 02d58cd253 f2fs: compress: disallow disabling compress on non-empty compressed file ... Compresse file and normal file has differ in i_addr addressing, specifically addrs per inode/block. So, we will face data loss, if we disable the compression flag on non-empty files. Therefore we should disallow not only enabling but disabling the compression flag on non-empty files.
