A concurrent drm_gem_handle_delete on the old\nhandle succeeds in this window, decrements handle_count to 0, and frees\nthe GEM object while the new handle's IDR entry still references it.\n\nNULL the old handle's IDR entry before dropping table_lock so that any\nconcurrent GEM_CLOSE on the old handle sees NULL and returns -EINVAL.\nRestore the old entry on the prime-bookkeeping error path.",
