Although by default we negotiate CIFS Unix Extensions for SMB1 mounts to Samba (and they work if the user does not specify "unix" or "posix" or "linux" on mount), and we do properly handle when a user turns them off with "nounix" mount parm. But with the changes to the mount API we broke cases where the user explicitly specifies the "unix" option (or equivalently "linux" or "posix") on mount with vers=1.0 to Samba or other servers which support the CIFS Unix Extensions. "mount error(95): Operation not supported" and logged: "CIFS: VFS: Check vers= mount option. SMB3.11 disabled but required for POSIX extensions" even though CIFS Unix Extensions are supported for vers=1.0 This patch fixes the case where the user specifies both "unix" (or equivalently "posix" or "linux") and "vers=1.0" on mount to a server which supports the CIFS Unix Extensions.

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 reStructuredText 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.
