[ Upstream commit 7a84394f02 ]
The setting of delay_retrans is applied to synchronous RPC operations
because the retransmit count is stored in same struct nfs4_exception
that is passed each time an error is checked. However, for asynchronous
operations (READ, WRITE, LOCKU, CLOSE, DELEGRETURN), a new struct
nfs4_exception is made on the stack each time the task callback is
invoked. This means that the retransmit count is always zero and thus
delay_retrans never takes effect.
Apply delay_retrans to these operations by tracking and updating their
retransmit count.

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.
