    ext4: avoid crash when inline data creation follows DIO write
    
    When inode is created and written to using direct IO, there is nothing
    to clear the EXT4_STATE_MAY_INLINE_DATA flag. Thus when inode gets
    truncated later to say 1 byte and written using normal write, we will
    try to store the data as inline data. This confuses the code later
    because the inode now has both normal block and inline data allocated
    and the confusion manifests for example as:
