Adrian Hunter a032ad87aa perf record: Fix done_fd wakeup event ... evlist__add_wakeup_eventfd() calls perf_evlist__add_pollfd() to add a non-perf-event to the evlist pollfds. Since commit 415ccb58f6 ("perf record: Introduce thread specific data array") that doesn't work because evlist pollfs is not polled and done_fd is not duplicated into thread-data. Patch "perf record: Fix way of handling non-perf-event pollfds" added a new approach that ensures file descriptors like done_fd are handled correctly by flagging them as fdarray_flag__non_perf_event. Fix by flagging done_fd as fdarray_flag__non_perf_event. Example: Before: $ sleep 3 & perf record -vv -p $! ... thread_data[0x55f44bd34140]: pollfd[0] <- event_fd=5 thread_data[0x55f44bd34140]: pollfd[1] <- event_fd=6 thread_data[0x55f44bd34140]: pollfd[2] <- event_fd=7 thread_data[0x55f44bd34140]: pollfd[3] <- event_fd=8 thread_data[0x55f44bd34140]: pollfd[4] <- event_fd=9 thread_data[0x55f44bd34140]: pollfd[5] <- event_fd=10 thread_data[0x55f44bd34140]: pollfd[6] <- event_fd=11 thread_data[0x55f44bd34140]: pollfd[7] <- event_fd=12 ... After: $ sleep 3 & perf record -vv -p $! ... thread_data[0x55a8ded89140]: pollfd[0] <- event_fd=5 thread_data[0x55a8ded89140]: pollfd[1] <- event_fd=6 thread_data[0x55a8ded89140]: pollfd[2] <- event_fd=7 thread_data[0x55a8ded89140]: pollfd[3] <- event_fd=8 thread_data[0x55a8ded89140]: pollfd[4] <- event_fd=9 thread_data[0x55a8ded89140]: pollfd[5] <- event_fd=10 thread_data[0x55a8ded89140]: pollfd[6] <- event_fd=11 thread_data[0x55a8ded89140]: pollfd[7] <- event_fd=12 thread_data[0x55a8ded89140]: pollfd[8] <- non_perf_event fd=4 ...
