| Subject: mm/vmstat: fix a W=1 clang compiler warning |
| Date: Thu, 12 Dec 2024 13:31:26 -0800 |
| |
| Fix the following clang compiler warning that is reported if the kernel is |
| built with W=1: |
| |
| ./include/linux/vmstat.h:518:36: error: arithmetic between different enumeration types ('enum node_stat_item' and 'enum lru_list') [-Werror,-Wenum-enum-conversion] |
| 518 | return node_stat_name(NR_LRU_BASE + lru) + 3; // skip "nr_" |
| | ~~~~~~~~~~~ ^ ~~~ |
