From: Yuntao Wang Date: Wed, 6 Dec 2023 10:43:17 +0000 (+0800) Subject: ACPI: NUMA: Optimize the check for the availability of node values X-Git-Tag: v6.8-rc1~169^2~1^3~1 X-Git-Url: https://repo.jachan.dev/linux.git/commitdiff_plain/ec0f96260737ae23dcad57463fdc32eba025b11d ACPI: NUMA: Optimize the check for the availability of node values The first_unset_node() function returns the first unused node in nodes_found_map. If all nodes are in use, the function returns MAX_NUMNODES. Use this return value to determine whether there are any available node values in nodes_found_map, eliminating the need to use nodes_weight() for this purpose.
