Linux kernel stable tree
e0b23d9953
At one point in time we had an optimisation that would not spin up a linked timeout timer when the master request successfully completes inline (during the first nowait execution attempt). We somehow lost it, so this patch restores it back. Note, that it's fine using io_arm_ltimeout() after the io_issue_sqe() completes the request because of delayed completion, but that that adds unwanted overhead.

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.
