libbpf, hashmap: Fix signedness warnings
Fixes the following warnings: hashmap.c: In function ‘hashmap__clear’: hashmap.h:150:20: error: comparison of integer expressions of different signedness: ‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Werror=sign-compare] 150 | for (bkt = 0; bkt < map->cap; bkt++) \ hashmap.c: In function ‘hashmap_grow’: hashmap.h:150:20: error: comparison of integer expressions of different signedness: ‘int’ and ‘size_t’ {aka ‘long unsigned int’} [-Werror=sign-compare] 150 | for (bkt = 0; bkt < map->cap; bkt++) \ Signed-off-by: Ian Rogers <irogers@google.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: Andrii Nakryiko <andriin@fb.com> Link: https://lore.kernel.org/bpf/20200515165007.217120-4-irogers@google.com
