Subject: [PATCH 11/18] 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.
