    make sure data is on disk before calling ->write_inode · 26821ed4
    Christoph Hellwig 提交于
    Similar to the fsync issue fixed a while ago in commit
    2daea67e we need to write for data to
    actually hit the disk before writing out the metadata to guarantee
    data integrity for filesystems that modify the inode in the data I/O
    completion path.  Currently XFS and NFS handle this manually, and AFS
    has a write_inode method that does nothing but waiting for data, while
    others are possibly missing out on this.
    
    Fortunately this change has a lot less impact than the fsync change
    as none of the write_inode methods starts data writeout of any form
    by itself.
