The previous safety check was introduced due to a bug in the kernel
where it would produce a traceback and hang the offending process.
This code was fixed in kernel 5.2.0:
8ae5b1d78d
Add a new configuration option that will allow disabling the safety
checks if a new enough kernel is in place. This configuration option
is necessary because some Linux distributions may backport drm, and thus
this commit but still need the feature to work.
