[ Upstream commit 4f1fffa2376922f3d1d506e49c0fd445b023a28e ] MS-SMB2 states that the header flag SMB2_FLAGS_REPLAY_OPERATION needs to be set when a command needs to be retried, so that the server is aware that this is a replay for an operation that appeared before. This can be very important, for example, for state changing operations and opens which get retried following a reconnect; since the client maybe unaware of the status of the previous open. This is particularly important for multichannel scenario, since disconnection of one connection does not mean that the session is lost. The requests can be replayed on another channel. This change also makes use of exponential back-off before replays and also limits the number of retries to "retrans" mount option value. Also, this change does not modify the read/write codepath.

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.
