Subject: [PATCH 3/7] nvme: track shared namespaces
Date: Thu, 09 Nov 2017 15:28:13 -0500 [thread overview]
Message-ID: <yq18tffw61u.fsf@oracle.com> (raw)
In-Reply-To: <20171109174450.17142-4-hch@lst.de> (Christoph Hellwig's message of "Thu, 9 Nov 2017 18:44:46 +0100")
Christoph,
> Introduce a new struct nvme_ns_head that holds information about an
> actual namespace, unlike struct nvme_ns, which only holds the
> per-controller namespace information. For private namespaces there is
> a 1:1 relation of the two, but for shared namespaces this lets us
> discover all the paths to it. For now only the identifiers are moved
> to the new structure, but most of the information in struct nvme_ns
> should eventually move over.
>
> To allow lockless path lookup the list of nvme_ns structures per
> nvme_ns_head is protected by SRCU, which requires freeing the nvme_ns
> structure through call_srcu.
