Subject: [PATCH] mm/cma: get nid from physical address
Date: Thu, 16 May 2024 17:17:01 +0800 [thread overview]
Message-ID: <20240516091701.1527002-1-yajun.deng@linux.dev> (raw)
The nid passed to cma_declare_contiguous_nid() may be NUMA_NO_NODE,
which is not the actual nid. To get the correct nid, we can get the nid
from physical address.
