Hello,

When I run sudo ./test.sh pid, it "hangs" indefinitely and I don't get a
trace.log file created. Here is the console output when I run (this is from
my second run):

+ pid=1318
+ mkdir /tmp/debug
mkdir: cannot create directory â/tmp/debugâ: File exists
+ mount -t debugfs debug /tmp/debug/
mount: debug already mounted or /tmp/debug/ busy
mount: according to mtab, debug is already mounted on /tmp/debug
+ echo 1318
+ echo function
+ echo 0
+ sudo cat /tmp/debug/tracing/trace_pipe
