Subject: mm/memblock: pass size instead of end to memblock_set_node()
X-Git-Tag: v6.15-rc5~30^2~2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=06eaa824fd239edd1eab2754f29b2d03da313003;p=thirdparty%2Fkernel%2Flinux.git

mm/memblock: pass size instead of end to memblock_set_node()

The second parameter of memblock_set_node() is size instead of end.

Since it iterates from lower address to higher address, finally the node
id is correct. But during the process, some of them are wrong.

Pass size instead of end.
