Old mount device syntax (source) has the following problems: - mounts to the same cluster but with different fsnames and/or creds have identical device string which can confuse xfstests. - Userspace mount helper tool resolves monitor addresses and fill in mon addrs automatically, but that means the device shown in /proc/mounts is different than what was used for mounting. New device syntax is as follows: cephuser@fsid.mycephfs2=/path Note, there is no "monitor address" in the device string. That gets passed in as mount option. This keeps the device string same when monitor addresses change (on remounts). Also note that the userspace mount helper tool is backward compatible. I.e., the mount helper will fallback to using old syntax after trying to mount with the new syntax.

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.
