	Exercise the function view without driving a terminal now that it has a stdio path. Keep the existing datasym record/report coverage and make a separate recording of the contended locks used by the futex hash benchmark. Always check the function table headers, table replacement, missing-iaddr diagnostic, and conflicting options. A machine can support c2c recording without capturing a contended sample, so report a skip when the hierarchy is empty rather than treating hardware sampling variance as a failure. When samples are available, check generic row shapes for all three hierarchy levels, their expanded fold signs, cacheline addresses, and the absence of trailing whitespace in the table body.

2026-09-25	perf tests c2c: Report skip when the workload fails	Jiebin Sun
	The workload path leaves err at 0 and returns, so the test exits 0 and is reported as a pass even though nothing was recorded and neither report invocation ran. The check_c2c_support() path above it already sets err=2. Set err=2 there as well so a failing workload is reported as a skip.
