The thread_global_copy subtest of the live migrate selftest creates a large number of threads and waits 10ms for them all to start. This is not enough time to wait for the threaded tasks to start, as some may need to wait for additional ring space to be granted. Threads that do so are at risk of getting stopped (signaled) in the middle of waiting for additional space, which can result in ERESTARTSYS getting reported erroneously by i915_request_wait. Instead of waiting a flat 10ms for the threads to start, wait 10ms per thread. This grants enough of a buffer for each thread to wait for additional ring space when needed.

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.
