Hi,
I got a issue which makes i_size and EOFBLOCKS_FL corrupted
on ext4 with xfstests 269.
In my environment (linux-3.5-rc7), this can be reproduced
once of 10 times trial.
Kernel: 3.5-rc7
Arch: x86_64
Step and log are as bellow, after xfstests 269, e2fsck outputs
i_size and EOFBLOCKS_FL corruption.
Is this an already known issue?

Hi Akira,
thanks for reporting this. Could you please try to use the most
recent e2fsprogs ? The EOFBLOCKS_FL has been removed from e2fsprogs
with:
010dc7b90d97b93907cbf57b3b44f1c1cad234f6 e2fsck: remove
EXT4_EOFBLOCKS_FL flag handling
and is about to be removed from kernel as well, so the EOFBLOCKS_FL
problem probably does not even matter. Though the i_size problem
might be real.
Not sure if it is a known problem, but I've certainly seen it before
with xfstest 269, though I have not had time to look at this yet. So
I guess I should :).
Thanks!

Thanks for comment, yes,
both e2fsck outputs I reported have gone with the latest e2fsprogs
(37c8db7b2078d0310e5676404e21cc143d8e4d56).

The patch also fixes i_size problem.
Because the last uninitialized extent (~~~ in below)
whose offset exceeds i_size and is not checked with the latest e2fsck.
