I could try that, but I did not want to touch g_file_storage. Instead I wanted to write my own block device driver which is used by g_file_storage in turn. So the daemon would be connected to my driver then .. I don't know, that sounds complicated. > Either that or look at the NFS kernel server code?

No, I didn't, but now that you mention it i can see the similarities - I will have a look. > Martyn > Thank you, Dan -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
