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 # Oxd7c [0x60]: failed to process type: 80 Error: Failed to process sample
Commit a2015516c5c0be932a69 ("perf record: Synthesize features before events in pipe mode") is the fix. Can we get this cherry-picked and applied?
This commit does not apply cleanly due to other changes. Is there something I can do to make it easier.
This line: If (data->is_pipe) { Must be changed to: If (file->is_pipe) {
Let me know if there is a more standard way of communicating cherry-picked changes for inclusion.

Indeed, I've resolved it the same.

Sending a mail to stable@vger.kernel.org is pretty much the standard way.
