Subject[PATCH 4.4 057/160] ima: fix showing large violations or runtime_measurements_count
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Eric Biggers <ebiggers@google.com>

commit 1e4c8dafbb6bf72fb5eca035b861e39c5896c2b7 upstream.

The 12 character temporary buffer is not necessarily long enough to hold
a 'long' value. Increase it.
