mainlining shenanigans
a637f4ae03
If smb3_notify() is called at mount point of CIFS, build_path_from_dentry() returns the pointer to kmalloc-ed memory with terminating zero (this is empty FileName to be passed to SMB2 CREATE request). This pointer is assigned to the `path` variable. Then `path + 1` (to skip first backslash symbol) is passed to cifs_convert_path_to_utf16(). This is incorrect for empty path and causes out-of-bound memory access. Get rid of this "increase by one". cifs_convert_path_to_utf16() already contains the check for leading backslash in the path.

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.
