Commit d38d272592737ea88a20 ("perf tools: Synthesize GROUP_DESC feature in pipe
mode") broke the LT 4.14 branch when using event groups in pipe-mode.
# perf record -e '{cycles,instructions,branches}' -- sleep 4 | perf report
# To display the perf.data header info, please use --header/--header-only
options

Commit a2015516c5c0be932a69 ("perf record: Synthesize features before events in pipe
mode") is the fix. Can we get this cherry-picked and applied?
I've queued d38d272592737ea88a20 for 4.14, thank you.
