* @page mfs_test_002_001 [2.1] Committing a transaction
*
* <h2>Description</h2>
* A set of new/existing records are written/erased within a
* transaction then the transaction is committed, the state is checked
* afterward.
*
* <h2>Test Steps</h2>
* - [2.1.1] Records 1, 2 and 3 are created, MFS_NO_ERROR is expected.
* - [2.1.2] Presence of records 1, 2 and 3 is verified, MFS_NO_ERROR
* is expected.
* - [2.1.3] Starting a transaction with sufficient pre-allocated
* space, MFS_NO_ERROR is expected.
* - [2.1.4] Atomically erasing record 1, updating record 2, reading
* record 3.
* - [2.1.5] Committing the transaction, MFS_NO_ERROR is expected.
* - [2.1.6] Testing outcome, records 1 must not be present, record 2
* must contain the new value and record 3 must be unchanged.
* - [2.1.7] Re-mounting the manage storage, MFS_NO_ERROR is expected.
* - [2.1.8] Testing outcome again after re-start.
* - [2.1.9] Performing a garbage collection, the result must not
* change.
* - [2.1.10] Testing outcome again after garbage collection.
