| |
Hi all,
I want to move there 3 id allocation from the simple way to ida. I have some questions about this:
1. We have a struct sas_host_attrs to hold the 3 int for the next id and a mutex for protect them. What's the purpose of the other 2 members (rphy_list and q). Are they related about these 3 id's allocation?
2. Since for ida, we need a static struct, and for there 3 ids, we need 3. Where can I store them? In the host's struct? Or somewhere else?
Thanks and waiting for your help, Yang
