clang warns:
fs/btrfs/delayed-inode.c:684:6: warning: variable 'total_data_size' set
but not used [-Wunused-but-set-variable]
int total_data_size = 0, total_size = 0;
^
1 warning generated.
This variable's value has been unused since commit fc0d82e103c7 ("btrfs:
sink total_data parameter in setup_items_for_insert"). Eliminate it.
