    ext4: Fix BUG_ON at fs/buffer.c:652 in no journal mode · 73b50c1c
    Curt Wohlgemuth authored
    Calls to ext4_handle_dirty_metadata should only pass in an inode
    pointer for inode-specific metadata, and not for shared metadata
    blocks such as inode table blocks, block group descriptors, the
    superblock, etc.
    
    The BUG_ON can get tripped when updating a special device (such as a
    block device) that is opened (so that i_mapping is set in
    fs/block_dev.c) and the file system is mounted in no journal mode.
