Perform various regression tests for ext4defrag subsystem Test1: Defragment file while other task does direct AIO Test2: Perform defragmentation on file under buffered AIO while third task does direct AIO to donor file Test3: Two defrag tasks use common donor file. Test4: Stress defragmentation. Several threads pefrorm fragmentation at random position use inplace=1 will allocate and free blocks inside defrag event improve load pressure. This test known to caught most known e4defrag bugs.
