From a40ecd7b3ccf520ff02da93e8d1ba6cd55c2e359 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 10 Oct 2011 01:08:04 -0700 Subject: udf: Rename udf_warning to udf_warn Rename udf_warning to udf_warn for consistency with normal logging uses of pr_warn. Rename function udf_warning to _udf_warn. Remove __func__ from uses and move __func__ to a new udf_warn macro that calls _udf_warn. Add \n's to uses of udf_warn, remove \n from _udf_warn. Coalesce formats.
