Subject: [PATCH -mmotm] efi: drop kmemleak_ignore() for page allocator
Date: Tue, 25 Dec 2018 21:35:34 -0500 [thread overview]
Message-ID: <20181226023534.64048-1-cai@lca.pw> (raw)
a0fc5578f1d (efi: Let kmemleak ignore false positives) is no longer
needed due to efi_mem_reserve_persistent() uses __get_free_page()
instead where kmemelak is not able to track regardless. Otherwise,
kernel reported "kmemleak: Trying to color unknown object at
0xffff801060ef0000 as Black"
