From fc8c0d9f44dc53e6912fa95793bc88968dc9f188 Mon Sep 17 00:00:00 2001 From: Eric Biggers Date: Thu, 23 Jun 2022 11:41:13 -0700 Subject: [PATCH] ext4/053: test changing test_dummy_encryption on remount The test_dummy_encryption mount option isn't supposed to be settable or changeable via a remount, so add test cases for this. This is a regression test for a bug that was introduced in Linux v5.17 and fixed in v5.19-rc3 by commit 85456054e10b ("ext4: fix up test_dummy_encryption handling for new mount API").
