[ Upstream commit deaef31bc1ec7966698a427da8c161930830e1cf ] If we loop for multishot receive on the initial attempt, and then abort later on to wait for more, we miss a case where we should be copying the io_async_msghdr from the stack to stable storage. This leads to the next retry potentially failing, if the application had the msghdr on the stack.

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.
