@jhol I may be misinterpreting AJ's comment, but I believe that he would like it to not store the xattr (rather than masking the stored value) when the flags are not in the mask list.  So, something more like:
```
static int fd_set_dos_attrib( int fd, ULONG attr )
{
    /* we only store the HIDDEN and SYSTEM attributes */
    if ((attr & XATTR_ATTRIBS_MASK) == 0)
        return 0;
...
```
