With the goal of removing the serialisation from around execbuf, we will no longer have the privilege of there being a single execbuf in flight at any time and so will only be able to inspect the user's flags within the carefully controlled execbuf context. i915_gem_evict_for_node() is the only user outside of execbuf that currently peeks at the flag to convert an overlapping softpinned request from ENOSPC to EINVAL. Retract this nicety and only report ENOSPC if the location is in current use, either due to this execbuf or another.

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.
