When using clang to build selftests with LLVM=1 in make commandline,
I hit the following compiler warning:
benchs/bench_bloom_filter_map.c:84:46: warning: result of comparison of constant 256
with expression of type '__u8' (aka 'unsigned char') is always false
[-Wtautological-constant-out-of-range-compare]
if (args.value_size < 2 || args.value_size > 256) {
~~~~~~~~~~~~~~~ ^ ~~~
The reason is arg.vaue_size has type __u8, so comparison "args.value_size > 256"
is always false.
This patch fixed the issue by doing proper comparison before assigning the
value to args.value_size. The patch also fixed the same issue in two
other places.
