Subject: [ 12/60] ext4: fix retry handling in ext4_ext_truncate()

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

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

From: Theodore Ts'o <tytso@....edu>

commit 94eec0fc3520c759831763d866421b4d60b599b4 upstream.

We tested for ENOMEM instead of -ENOMEM.   Oops.
