If we enter with requests pending and performm cancelations, we'll have a different inflight count before and after calling prepare_to_wait(). This causes the loop to restart. If we actually ended up canceling everything, or everything completed in-between, then we'll break out of the loop without calling finish_wait() on the waitqueue. This can trigger a warning on exit_signals(), as we leave the task state in TASK_UNINTERRUPTIBLE. Put a finish_wait() after the loop to catch that case.

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.
