From fcc742c294c9c189e7040a3de8528ac6f8ee13ef Mon Sep 17 00:00:00 2001 From: Theodore Ts'o Date: Sat, 12 Apr 2014 12:45:25 -0400 Subject: [PATCH] ext4: use i_size_read in ext4_unaligned_aio() commit 6e6358fc3c3c862bfe9a5bc029d3f8ce43dc9765 upstream. We haven't taken i_mutex yet, so we need to use i_size_read().
