From 5ceb8b554dcaaf6844415cd2616ce2e0132530fa Mon Sep 17 00:00:00 2001 From: Fabian Frederick Date: Wed, 8 Apr 2015 21:23:51 +0200 Subject: udf: Return -ENOMEM when allocation fails in udf_get_filename() Return -ENOMEM when allocation fails in udf_get_filename(). Update udf_pc_to_char(), udf_readdir(), and udf_find_entry() to handle the error appropriately. This allows us to pass appropriate error to userspace instead of corrupting symlink contents by omitting some path elements.
