From fadc0d8be4dfca80f6c568bc5874931893c6709b Mon Sep 17 00:00:00 2001 From: David Sterba Date: Sun, 20 Nov 2011 07:33:38 -0500 Subject: btrfs: fix stat blocks accounting Round inode bytes and delalloc bytes up to real blocksize before converting to sector size. Otherwise eg. files smaller than 512 are reported with zero blocks due to incorrect rounding.
