We use cluster unit and block unit for different structure members. For
example, in struct ext4_prealloc_space, pa_lstart and pa_pstart are in
block unit while pa_len and pa_free are in cluster unit; in struct
ext4_free_extent, fe_logical is in block unit while fe_start and fe_len
are in cluster unit. The first five patches fix wrong unit use in
mballoc.
The rest is random bugfix and cleanup to mballoc, More details can be
found in respective patches.
Besides, "kvm-xfstest smoke" passes all test.
Thanks!
