This is a regression testcase to check whether we will handle database inode dirty status correctly: 1. create a regular file, and write data into the file 2. start transaction on the file (via F2FS_IOC_START_ATOMIC_WRITE) 3. write transaction data to the file 4. rename the file 5. commit and end the transaction (via F2FS_IOC_COMMIT_ATOMIC_WRITE) 6. drop caches in order to call f2fs_evict_inode() It expects kernel panic will gone after we apply commit 03511e936916 ("f2fs: fix inconsistent dirty state of atomic file").
