From d9bc85de46cad90851c346b592005090674b7669 Mon Sep 17 00:00:00 2001 From: Libing Zhou Date: Thu, 15 Oct 2020 20:13:42 -0700 Subject: ROMFS: support inode blocks calculation When use 'stat' tool to display file status, the 'Blocks' field always in '0', this is not good for tool 'du'(e.g.: busybox 'du'), it always output '0' size for the files under ROMFS since such tool calculates number of 512B Blocks. This patch calculates approx. number of 512B blocks based on inode size.
