The call to shmem_file_setup() in drm_gem_object_alloc() should properly
increment the IMA counters and the fput() in
drm_gem_object_free_common() should decrement them.
I noticed the 'bump' comment in 'include/drm/drmP.h' doesn't match the
code, but in fact does the exact opposite. Not sure if this is related.
static inline void
drm_gem_object_handle_unreference(struct drm_gem_object *obj)
{
if (obj == NULL)
return;
/*
* Must bump handle count first as this may be the last
* ref, in which case the object would disappear before we
* checked for a name
*/
kref_put(&obj->handlecount, drm_gem_object_handle_free);
drm_gem_object_unreference(obj);
}
