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=E2=80=99t =
get whole backtrace.
The backtrace gets =E2=80=9C0x0 (inexact)=E2=80=9D
Is there any means that I could get the whole backtrace information?=
