From 9bf2c6b834f4caad82b3e2d962c266153d39e411 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 4 Mar 2008 13:10:29 +0100 Subject: [PATCH] udf: Remove checking of existence of filename in udf_add_entry() We don't have to check whether a directory entry already exists in a directory when creating a new one since we've already checked that earlier by lookup and we are holding directory i_mutex all the time.
