Xiao Yang d12d7bf92b selftests/ftrace: Check the first record for kprobe_args_type.tc ... [ Upstream commit f0c0d0cf590f71b2213b29a7ded2cde3d0a1a0ba ] It is possible to get multiple records from trace during test and then more than 4 arguments are assigned to ARGS. This situation results in the failure of kprobe_args_type.tc. For example: ----------------------------------------------------------- grep testprobe trace ftracetest-5902 [001] d... 111195.682227: testprobe: (_do_fork+0x0/0x460) arg1=334823024 arg2=334823024 arg3=0x13f4fe70 arg4=7 pmlogger-5949 [000] d... 111195.709898: testprobe: (_do_fork+0x0/0x460) arg1=345308784 arg2=345308784 arg3=0x1494fe70 arg4=7 grep testprobe trace sed -e 's/.* arg1=\(.*\) arg2=\(.*\) arg3=\(.*\) arg4=\(.*\)/\1 \2 \3 \4/' ARGS='334823024 334823024 0x13f4fe70 7 345308784 345308784 0x1494fe70 7' ----------------------------------------------------------- We don't care which process calls do_fork so just check the first record to fix the issue.
