perf tools: Use O_LARGEFILE to open perf data file
Open perf data file with O_LARGEFILE flag since its size is easily larger that 2G. For example: # rm -rf perf.data # ./perf kmem record sleep 300 [ perf record: Woken up 0 times to write data ] [ perf record: Captured and wrote 3142.147 MB perf.data (~137282513 samples) ] # ll -h perf.data -rw------- 1 root root 3.1G .....
