Juhee Kang 0f84b7521f samples: bpf: Fix tracex7 error raised on the missing argument ... BugLink: https://bugs.launchpad.net/bugs/1946802 [ Upstream commit 7d07006f05 ] The current behavior of 'tracex7' doesn't consist with other bpf samples tracex{1..6}. Other samples do not require any argument to run with, but tracex7 should be run with btrfs device argument. (it should be executed with test_override_return.sh) Currently, tracex7 doesn't have any description about how to run this program and raises an unexpected error. And this result might be confusing since users might not have a hunch about how to run this program. // Current behavior # ./tracex7 sh: 1: Syntax error: word unexpected (expecting ")") // Fixed behavior # ./tracex7 ERROR: Run with the btrfs device argument! In order to fix this error, this commit adds logic to report a message and exit when running this program with a missing argument. Additionally in test_override_return.sh, there is a problem with multiple directory(tmpmnt) creation. So in this commit adds a line with removing the directory with every execution.
