[ Upstream commit26a57cb355] The kernel always logs the unique subsystem name for a discovery controller, even in the case user space asked for the well known. This has lead to confusion as the logs of nvme-cli and the kernel logs didn't match. First, nvme-cli connects to the well known discovery controller to figure out if it supports TP8013. If so then nvme-cli disconnects and connects to the unique discovery controller. Currently, the kernel show that user space connected twice to the unique one. To avoid further confusion, show the well known discovery controller if user space asked for it: $ nvme connect-all -v -t tcp -a 192.168.0.1 nvme0: nqn.2014-08.org.nvmexpress.discovery connected nvme0: nqn.2014-08.org.nvmexpress.discovery disconnected nvme0: nqn.discovery connected kernel log: nvme nvme0: new ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery", addr 192.168.0.1:8009 nvme nvme0: Removing ctrl: NQN "nqn.2014-08.org.nvmexpress.discovery" nvme nvme0: new ctrl: NQN "nqn.discovery", addr 192.168.0.1:8009 Fixes:e5ea42faa7("nvme: display correct subsystem NQN") Signed-off-by: Daniel Wagner <dwagner@suse.de> Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Sasha Levin <sashal@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
