Oh, yes, I messed up the "Fixes" line then. It should write:
Fixes: 5a640967 ("tty/n_gsm.c: fix a memory leak in gsmld_open()")
that's Okay. :)
I have one confusion. As there is field gsm->num to store the index of
gsm_mux[]. so in gsm_cleanup_mux(), why we still use for-loop to find
this mux?
In error handle path, for example, the call trace in this patch, as we
failed to activate it and the
gsm->num is invalid(and the value is 0). we can just modify the codes
like below:
if(gsm_mux[gsm->num] == gsm)
....other work
else
return;
I think it would work, and the logic is correct. Or I just miss
something important?
Yup, it looks like a cleanup. Could you prepare a separate patch for that?
yes, I will do that :)
Something like this:
/* open failed before registering => nothing to do */
if (gsm_mux[gsm->num] != gsm)
return;
spin_lock(&gsm_mux_lock);
gsm_mux[gsm->num] = NULL;
spin_unlock(&gsm_mux_lock);
looks pretty good, thanks.
thanks,
thanks
