I think there is a big benefit when these are all renamed to "drm_dev". I have no strong preference here though, so "drmdev" or "drm" are fine for me, too. Let the bikesheding begin! Some statistics: $ git grep -ohE 'struct drm_device *\* *[^ (),;]*' v6.5-rc1 | sort | uniq -c | sort -n 1 struct drm_device *adev_to_drm 1 struct drm_device *drm_ 1 struct drm_device *drm_dev 1 struct drm_device *drm_dev 1 struct drm_device *pdev 1 struct drm_device *rdev 1 struct drm_device *vdev 2 struct drm_device *dcss_drv_dev_to_drm 2 struct drm_device **ddev 2 struct drm_device *drm_dev_alloc 2 struct drm_device *mock 2 struct drm_device *p_ddev 5 struct drm_device *device 9 struct drm_device * dev 25 struct drm_device *d 95 struct drm_device * 216 struct drm_device *ddev 234 struct drm_device *drm_dev 611 struct drm_device *drm 4190 struct drm_device *dev This series starts with renaming struct drm_crtc::dev to drm_dev. If it's not only me and others like the result of this effort it should be followed up by adapting the other structs and the individual usages in the different drivers.I think this is an unnecessary change. In drm, a dev is usually a drm device, i.e. struct drm_device *. As shown by the numbers above.I'd really prefer this patch (series or single) is not accepted. This will cause problems for everyone cherry-picking patches to a downstream kernel (LTS or distro tree). I usually wouldn't expect sympathy here, but the questionable benefit does not outweigh the cost IM[biased]O.
I agree.
SeanIf folks insist on following through with this anyway, I'm firmly in the camp the name should be "drm" and nothing else. BR, Jani. -- Jani Nikula, Intel Open Source Graphics Center
