Add a convenience script for adding new injection cookies and filter for
actual testing.
- ./inject-error new - return new unique cookie
- ./inject-error file tune/change-csum.c - show all cookies in the given
file (takes regexp)
Example usage:
for i in $(./inject-error file tune/change-csum.c | awk '{print $1}') ; do
echo "Inject $i"
export INJECT="$i"
rm img
cp --reflink img.filled img
./btrfstune --csum blake2 img
btrfs check img
done
Where 'img' is a filesystem with sample files and directories.
