commit44805b0e62upstream. Currently the client translates O_SYNC and O_DIRECT flags into corresponding SMB create options when openning a file. The problem is that on reconnect when the file is being re-opened the client doesn't set those flags and it causes a server to reject re-open requests because create options don't match. The latter means that any subsequent system call against that open file fail until a share is re-mounted. Fix this by properly setting SMB create options when re-openning files after reconnects.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
