ttm and kvm are now the last user of register_shrinker that doesn't propagate the return code to its caller, all other callers got fixed in one way or another.
I tried to fix this one too, but couldn't come up with a proper way of unwinding both kobject_init_and_add() and ttm_pool_mm_shrink_init():
ret = kobject_init_and_add(&_manager->kobj, &ttm_pool_kobj_type, &glob->kobj, "pool"); if (unlikely(ret != 0)) { kobject_put(&_manager->kobj); _manager = NULL; return ret; }
ttm_pool_mm_shrink_init(_manager);
Calling kobject_put() after a failed kobject_init_and_add() seemed wrong, and it also appears to be missing a kfree(), so I didn't want to mess it up any further. Added a few people to Cc that touched this file most, maybe one of them can have a look, or they already have a patch waiting to get merged.

That isn't urgent, isn't it? So I would say I put it on my TODO list and I'm going to take care of it no later than 4.17.
Otherwise Roger or me could take a look tomorrow.

My understanding is that the warning will be in 4.16, so the fix should be as well, if only to get a clean build again. There were around a dozen such warnings when the warn_unused_result got added, but the others are all fixed in linux-next.
This is how the flag got added:

Calling kobject_put() after a failed kobject_init_and_add() seemed wrong, and it also appears to be missing a kfree(), so I didn't want to mess it up any further.
ttm_pool_kobj_release will do that, so no need kfree() here. I will fix this warning today. Thanks.
