Subject: nvme-print: check namespace in nvme_ctrl_for_each_path()
X-Git-Tag: v2.0-rc1~9^2
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=548d9cdd6503fc284f9b78a843ef6ba23f6387da;p=users%2Fsagi%2Fnvme-cli.git

nvme-print: check namespace in nvme_ctrl_for_each_path()

We should check if the namespace is available when scanning all
paths in nvme_ctrl_for_each_path(); a controller might be resetting
and might not be able to access the namespaces here.
