In this patch, we simulate race case in between sqlite atomic write and direct IO w/ below steps: 1. create a regular file, and initialize it w/ 0xff data 2. start transaction (via F2FS_IOC_START_ATOMIC_WRITE) on it 3. write transaction data 4. trigger direct read/write IO on it to check whether it fails or not 5. commit and end the transaction (via F2FS_IOC_COMMIT_ATOMIC_WRITE) This is a regression test to check handling of race condition in between atomic_write and direct IO.
