Sorry I didn't look good at diff of two patches, my mistake.

Yes, I actually test v3 patch, but not on the top of dev branch,
instead the dev branch was on the top of v3 patch.
(but it changes nothing), with "-O bigalloc" and "-o block_validity"
Also today I recheck this using kvm/qemu, with v3 patch on the top of
ext4 dev branch, and still nothing, here is last commits:
62f5f55 ext4: initialize multi-block allocator before checking block descriptors
eb3e7ab ext4: fix partial cluster handling for bigalloc file systems
97d3979 ext4: delete path dealloc code in ext4_ext_handle_uninitialized_extents
The only difference between your tests and my, is that you have i386,
while i have x86_64. But I really doubt that this is significantly.
