Subject: [PATCH] udf: Support splicing to file
Git-commit: 6c78973da0b11255d2668518ac1baba4c581811a
Patch-mainline: v6.1-rc1
References: bsc#1210770

Add explicit support for splicing from pipe to file through
iter_file_splice_write(). Commit 36e2c7421f02 ("fs: don't allow splice
read/write without explicit ops") removed the default .splice_write
operation which effectively removed UDF support for splicing from pipe.
