Re: [PATCH 3/5] nvme: track shared namespaces

From: Sagi Grimberg <sagi@grimberg.me>

Also in: linux-nvme 

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.
Can you remind me why isn't rcu sufficient? Can looking up a
path (ns from head->list) block?
