From fdf2657bc81b10dee856ec9f8fe5b201c0561e9d Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Tue, 18 Nov 2014 18:29:10 +0100 Subject: udf: One function call less in udf_fill_super() after error detection The iput() function was called in up to three cases by the udf_fill_super() function during error handling even if the passed data structure element contained still a null pointer. This implementation detail could be improved by the introduction of another jump label.
