[PATCH v1 1/3] f2fs/015: clear MKFS_OPTIONS and MOUNT_OPTIONS

[PATCH v1 1/3] f2fs/015: clear MKFS_OPTIONS and MOUNT_OPTIONS

[Joanne Chang]

Currently, residual options can interfere with checking the mount
behavior of the listed MKFS_OPTIONS and MOUNT_OPTIONS. For example,
"Option#120: test_dummy_encryption" should fail with the listed
options but succeeds if “MKFS_OPTIONS=encrypt” is preset. By
explicitly clearing MKFS_OPTIONS and MOUNT_OPTIONS, the test’s
reliability can be improved.

f2fs/015.out is also updated to expect failure for cases that require
additional mkfs attributes to mount.

[PATCH v1 2/3] f2fs/016: add test cases for test_dummy_encryption mount option

[Joanne Chang]

Add test cases to verify f2fs's support for different versions of the
"test_dummy_encryption" mount option.

To ensure test robustness, the MKFS_OPTIONS and MOUNT_OPTIONS are
cleared. This prevents additional options from interfereing with the
test results.

To Zorro,

The changes look good to me, though, still I want to confirm that whether
it is recommended or not to add new cases in old testcase.

Thanks,

Hi Chao,

I think this case isn't a regression test to uncover a known bug, it's a
basic mount options test for f2fs. So that makes sense to me to add
"test_dummy_encryption" into f2fs/016, especially if it doesn't need to
bring in more _require_* restriction (right?) .

Zorro,

Thanks for the confirmation, I agree w/ that.

[PATCH v1 3/3] f2fs/{019,020}: clear MOUNT_OPTIONS alongside MKFS_OPTIONS

[Joanne Chang]

Currently, f2fs/019 and f2fs/020 only clears MKFS_OPTIONS. This causes
the tests to fail when leftover MOUNT_OPTIONS depend on unapplied
MKFS_OPTIONS. So MOUNT_OPTIONS should also be cleared to ensure reliable
mounting.
