Not sure I can agree it's pointless, since it recently took me a while
to realize that unlocking bo->resv is essentially the same as
unreserving the BO.
Ok in this case let's call this confusing. But yeah that
__ttm_bo_unreserv(bo), reservation_object_unlock(bo->resv) and
ww_mutex_unlock(&bo->resv->lock) are essentially the same thing is
exactly what I want to fix here.
Anyway, this breaks the qxl driver:
drivers/gpu/drm//qxl/qxl_release.c: In function ‘qxl_release_fence_buffer_objects’:
drivers/gpu/drm//qxl/qxl_release.c:472:3: error: implicit declaration of function ‘__ttm_bo_unreserve’; did you mean ‘ttm_bo_unreserve’? [-Werror=implicit-function-declaration]
__ttm_bo_unreserve(bo);
^~~~~~~~~~~~~~~~~~
ttm_bo_unreserve
Thanks for pointing this out, going to respin.
Christian.
