Handle trailing and leading separators when parsing UNC and prefix paths in smb3_parse_devname(). Then, store the sanitised paths in smb3_fs_context::source. This fixes the following cases $ mount //srv/share// /mnt/1 -o ... $ cat /mnt/1/d0/f0 cat: /mnt/1/d0/f0: Invalid argument The -EINVAL was returned because the client sent SMB2_CREATE "\\d0\f0" rather than SMB2_CREATE "\d0\f0". $ mount //srv//share /mnt/1 -o ... mount: Invalid argument The -EINVAL was returned correctly although the client only realised it after sending a couple of bad requests rather than bailing out earlier when parsing mount options.

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.
