Some of the stuff also looks very suspicious. - Improve the contended checks a bit to make sure we only get an -EALREADY when we expect it. - Add an interruptible backoff function just to be complete (since otherwise the interruptible locking function makes 0 sense at all). - Inline the slowpath (due to the above). - Move ww_acquire_fini into drm_modeset_acquire_fini. I suspect this has been due to the confusion about the lifetime of the acquire ctx wrt the locking retry loop. - Drop uapi changes, they really shouldn't be in this patch. - s/!ret/ret == 0/ because I got confused - I tend to use !ret only for booleans or pointers, not for errno integer return values Daniel Vetter
