From 0bc5e18aace8d2535adc57cfa95c2481e94d60f7 Mon Sep 17 00:00:00 2001 From: Chris Mason Date: Thu, 9 Feb 2012 09:29:19 -0500 Subject: [PATCH] btrfsck: make sure to dirty all block groups as we fix accounting The code that corrects the count of bytes used in each block group was only marking block groups dirty when they contained extents. This fixes things to dirty all the block groups, so any empty block groups are written with their correct (zero) count.
