pdev->p2pdma is normally accessed through provider-owned references, but pci_p2pmem_find_many() and the p2pmem sysfs attributes may race with driver unbind.

Document initialization, teardown, and how the release grace period protects both the P2PDMA state and its optional allocation pool.

Reads correct to me.

Thanks, Logan. Unfortunately, I'm inclined to drop this patch. AI review makes it nearly impossible to write the description without complaints.

If I use my own words to describe the lifetime, the tools complain about almost every word or sentence. If I let the tools write it instead, the result is complete junk that merely describes basics already obvious from the code itself.

Thanks
