[PATCH 3.4 42/43] ext4: use i_size_read in ext4_unaligned_aio()

[Greg Kroah-Hartman]

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Theodore Ts'o <tytso@xxxxxxx>

commit 6e6358fc3c3c862bfe9a5bc029d3f8ce43dc9765 upstream.

We haven't taken i_mutex yet, so we need to use i_size_read().
