A multishot timeout submission will repeatedly generate completions with the IORING_CQE_F_MORE cflag set. Depending on the value of the `off' field in the submission, these timeouts can either repeat indefinitely until cancelled (`off' = 0) or for a fixed number of times (`off' > 0). Only noseq timeouts (i.e. not dependent on the number of I/O completions) are supported. An indefinite timer will be cancelled if the CQ ever overflows.

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.
