Date: Thu, 23 Jun 2022 11:41:13 -0700 From: Eric Biggers <ebiggers@...nel.org> To: fstests@...r.kernel.org Cc: linux-ext4@...r.kernel.org, linux-fscrypt@...r.kernel.org, Lukas Czerner <lczerner@...hat.com> Subject: [xfstests PATCH v2] ext4/053: test changing test_dummy_encryption on remount From: Eric Biggers <ebiggers@...gle.com> 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").
