Subject: [BUG] 2.6.27-rc1 - ext4 e2fsck false prompting for fixing i_size
 of Inode 

Hi,

While running e2fsck over the partition which was ext4 mounted,
the e2fsck suggest fixing the Inode with the same i_size value
as the existing one.

The partition is of size 135GB, I created 13 files each of 10GB
using  dd if=/dev/zero of=<filename> bs=1024 count=10485760 and
filesystem check on the partition prompts for following fixing

/usr/local/e2fsprogs/sbin/e2fsck -fnv /dev/sdb5
e2fsck 1.41.0 (10-Jul-2008)
