From 60b99a1b9fa731453e1b69a3e0b3e4dcab7a6ea5 Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Tue, 24 Jan 2023 12:07:37 +0100 Subject: udf: Convert in-ICB files to use udf_write_begin() Switching address_space_operations while a file is used is difficult to do in a race-free way. To be able to use single address_space_operations in UDF, make in-ICB files use udf_write_begin().
