Subject: [PATCH v2 1/2] perf util: Change intlist int to unsigned long
Date: Fri, 29 Jan 2021 15:08:53 +0800 [thread overview]
Message-ID: <20210129070854.29312-1-yao.jin@linux.intel.com> (raw)
This is to let intlist support address.
One potential problem is it can't support negative number. But
so far, there is no such kind of use case.
