Subject: [PATCH v15 1/3] /proc/pid/status: Add support for architecture specific output
Date: Tue, 16 Apr 2019 14:32:48 +0800 [thread overview]
Message-ID: <20190416063250.7514-1-aubrey.li@linux.intel.com> (raw)
The architecture specific information of the running processes could
be useful to the userland. Add support to examine process architecture
specific information externally.
