4 | Subject: [PATCH] perf cpumap: Make counter as unsigned ints | ||
5 | |||
6 | These are loop counters which is inherently unsigned. Therefore make | ||
7 | them unsigned. Moreover it also fixes alloc-size-larger-than | ||
8 | error with gcc-13, where malloc can be called with (-1) due to tmp_len | ||
9 | being an int type. | ||
10 | |||
11 | Fixes | ||
12 | | cpumap.c:366:20: error: argument 1 range [18446744065119617024, 18446744073709551612] exceeds maximum object size 9223372036854775807 [-Werror=alloc-size-larger-than=] | ||
