The schedule() call there really never did anything at least since the introduction of the EEVDF scheduler, but now I found a case where we permanently hang in a loop of -ERESTARTNOINTR (due to locking.) Work around it by making any syscalls with error return take time (and then schedule after) so we cannot hang in such a loop forever.

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 reStructuredText 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.
