f2fs: test for race condition in between atomic_write and gc
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
6. check consistency of transaction
This is a regression test to check handling of race condition in
between atomic_write and GC.
