In some implementations of the remote firmware, an intent request acknowledgment is sent when it's determined if the intent allocation will be fulfilled, but then the intent is queued after the acknowledgment. The result is that upon receiving a granted allocation request, the search for the newly allocated intent will fail and an additional request will be made. This will at best waste memory, but if the second request is rejected the transaction will be incorrectly rejected. Take the incoming intent into account in the wait to mitigate this problem. The above scenario can still happen, in the case that, on that same channel, an unrelated intent is delivered prior to the request acknowledgment and a separate process enters the send path and picks up the intent. Given that there's no relationship between the acknowledgment and the delivered (or to be delivered intent), there doesn't seem to be a solution to this problem.

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.
