This is present upstream as well (3.7.0-rc7). In fact it is not even ext4
specific. I can easily reproduce this on btrfs, ext3, vfat. I suspect that this
would be reproducible on every file system which does not implement its own
read/write exclusion as xfs does.

MM people should really take a look at this as well since we are expecting the
read/write to/from the single page to be atomic, but this looks like that it
might not be true.

Thanks!
