When file is changed using notepad on read-only share(read_only = yes in ksmbd.conf), There is a problem where existing data is truncated. notepad in windows try to O_TRUNC open(FILE_OVERWRITE_IF) and all data in file is truncated. This patch don't allow O_TRUNC open on read-only share and add KSMBD_TREE_CONN_FLAG_WRITABLE check in smb2_set_info().

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.
