No one else has reported any problems to date, and there are only two
changes in ext4 code between v4.4.7 and v4.4.8, neither of which seem
at all likely to cause file system corruption.

ee8516a ext4: ignore quota mount options if the quota feature is enabled
321299a ext4: add lockdep annotations for i_data_sem

If you can send us the "EXT4-fs error" message that would have been
logged before the file system went read-only, or the output from
e2fsck, that might be helpful in matching up your report from any
others, or to have some insight into what might have happened.

Unfortunately, without any more information there's not much we can do
with your report other than to keep an ear out in case anyone else
complains.

Thanks,
