When cap.max_inline_data is 0, it will be modified to 1 since roundup_pow_of_two(0) == 1, which violates users' expectations. Here fix it.

Just use min3() instead.
Sorry I don't get it. Only two values are compared here

min3(attr->cap.max_inline_data, roundup_pow_of_two(attr->cap.max_inline_data), ctx->max_inline_data)

min3(attr->cap.max_inline_data, roundup_pow_of_two(attr->cap.max_inline_data), ctx->max_inline_data)
This is wrong when attr->cap.max_inline_data is not power of 2

I tried, but the result was really not what we expected, since roundup_pow_of_two(attr->cap.max_inline_data) will never be smaller than attr->cap.max_inline_data. What we want is the roundup_pow_of_two() value.
attr->cap.max_inline_data = 3
roundup_pow_of_two(attr->cap.max_inline_data) = 4
ctx->max_inline_data = 1024
min3 result = 3
