Why should a fix for a bona-fide issue be dropped due to political reasons? This doesn't make sense to me. This just hurts miserable i915 users even more. If my patch is going to be dropped, it should be replaced by a different fix at the same time. Also, the mainline fixes just *happen* to fix this deadlock by removing the mutex lock from the path in question and creating multiple other bugs in the process that had to be addressed with "Fixes:" commits. The regression potential was too high to include those patches for a "stable" kernel, so I made this patch which fixes the issue in the simplest way possible. We put this patch into Ubuntu now as well, because praying for a response from i915 maintainers while the 20.04 release was on the horizon was not an option. > There is an another similar thread where there's jumping into > conclusions and doing ad-hoc patches for already fixed issues: > > https://lore.kernel.org/dri-devel/20200414144309.GB2082@sultan-box.localdomain/ Maybe this wouldn't have happened if I had received a proper response for that issue on gitlab from the get-go... Instead I got the run-around from Chris claiming that it wasn't an i915 bug: https://gitlab.freedesktop.org/drm/intel/issues/1599 > I appreciate enthusiasm to provide fixes to i915 but we should > continue do the regular due diligence to make sure we're properly > fixing bugs in upstream kernels.

I really see no reason to send anything there anymore, when the vast majority of community-sourced bug reports go ignored.
