Test that we will simulate sqlite atomic write logic 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 foreground GC to migrate data block of the file 5. commit and end the transaction (via F2FS_IOC_COMMIT_ATOMIC_WRITE) 6. check consistency of transaction w/ in-memory and on-disk data This is a regression test to check handling of race condition in between atomic_write and GC.
