Hi Maintainers,
I have a question about "__ref" in Linux kernel.
When I looked into the __irq_alloc_descs(), I found it tagged a "__ref" mark, but I didn't find that it referenced code or data from init section.
So, I confuse why the "__ref" is needed in __irq_alloc_descs()? any other reasons?
And after I tested, seems "__ref" just puts the code into a different section that is not checked by modpost. It does not affect the performance whether it is tagged or not. Is it right?
Thanks, dou.
