From: Pratik Farkase <[email protected]> The 'pgrep match against full process name' test uses pgrep -f with a regex pattern close to ARG_MAX in size (~100KB). This intermittently fails on qemuriscv64 where the process cmdline may not be fully visible in /proc/<pid>/cmdline at the time pgrep reads it, or the large regex match times out under TCG emulation.
Skip this single test case while keeping all other 30+ pgrep tests which are reliable.
