    Btrfs: implement FS_IOC_GETFLAGS/SETFLAGS/GETVERSION · 6cbff00f

    Add support for the standard attributes set via chattr and read via
    lsattr.  Currently we store the attributes in the flags value in
    the btrfs inode, but I wonder whether we should split it into two so
    that we don't have to keep converting between the two formats.
    
    Remove the btrfs_clear_flag/btrfs_set_flag/btrfs_test_flag macros
    as they were confusing the existing code and got in the way of the
    new additions.
    
    Also add the FS_IOC_GETVERSION ioctl for getting i_generation as it's
    trivial.
