Subject: Can't get whole backtrace
Date: Tue, 25 Jan 2022 20:58:15 +0800 [thread overview]

Hi guys,
I am trying to get backtrace of the function wb_wakeup() in fs/fs-writeback.c
My systemstp code is below
probe kernel.statement("wb_wakeup@fs/fs-writeback.c"){
printf("wb_wakeup exec name:%s \n",execname())
print_backtrace()
}
It successfully hoop the function that I am interested but can’t get whole backtrace.
The backtrace gets “0x0 (inexact)”
Is there any means that I could get the whole backtrace information?
