Hi,

I don't mean to discourge test systems, but looking at this, I just go
"meh" and delete it - it doesn't seem to contain obviously useful
information. One has to read every damn line to see if there's something
of relevence, which I for one am not going to do.

Is there some kind of improvement that could be done to this to make it
more useful - such as only sending the warnings/errors to the
appropriate mailing lists for those - rather than grouping everything
together into one email. At least that should make the stuff (a) more
relevant and (b) easier to parse.

Russell.

Hi,

I don't mean to discourge test systems, but looking at this, I just go
"meh" and delete it - it doesn't seem to contain obviously useful
information. One has to read every damn line to see if there's something
of relevence, which I for one am not going to do.

Is there some kind of improvement that could be done to this to make it
more useful - such as only sending the warnings/errors to the
appropriate mailing lists for those - rather than grouping everything
together into one email. At least that should make the stuff (a) more
relevant and (b) easier to parse.

Russell.

Hi,

I don't mean to discourge test systems, but looking at this, I just go
"meh" and delete it - it doesn't seem to contain obviously useful
information. One has to read every damn line to see if there's something
of relevence, which I for one am not going to do.

Is there some kind of improvement that could be done to this to make it
more useful - such as only sending the warnings/errors to the
appropriate mailing lists for those - rather than grouping everything
together into one email. At least that should make the stuff (a) more
relevant and (b) easier to parse.

Russell.

Thanks for the feedback Russell, we will further consider how to make this
summary report more helpful, and reduce unnecessary distribution to many
mailing list.

Typically, 0day ci sends 2 kinds of reports, one is bisected report, which
has specific warning/error as you mentioned to related receivers. Such as
https://lore.kernel.org/all/202207130344.AUqExE4E-lkp@intel.com/

The other is this summary, we want to give an overview to the owner for the
head status. And we will re-consider the appropriate audiences for the mail
and the contents to make it clear.

Thanks for the feedback Russell, we will further consider how to make this
summary report more helpful, and reduce unnecessary distribution to many
mailing list.

Typically, 0day ci sends 2 kinds of reports, one is bisected report, which
has specific warning/error as you mentioned to related receivers. Such as
https://lore.kernel.org/all/202207130344.AUqExE4E-lkp@intel.com/

The other is this summary, we want to give an overview to the owner for the
head status. And we will re-consider the appropriate audiences for the mail
and the contents to make it clear.

Thanks for the feedback Russell, we will further consider how to make this
summary report more helpful, and reduce unnecessary distribution to many
mailing list.

Typically, 0day ci sends 2 kinds of reports, one is bisected report, which
has specific warning/error as you mentioned to related receivers. Such as
https://lore.kernel.org/all/202207130344.AUqExE4E-lkp@intel.com/

The other is this summary, we want to give an overview to the owner for the
head status. And we will re-consider the appropriate audiences for the mail
and the contents to make it clear.

IMHO I think that adding '__rcu' annotation would remove the warning:

diff --git a/include/linux/tty.h b/include/linux/tty.h
index 7b0a5d478ef6..278b84f04d20 100644
--- a/include/linux/tty.h
+++ b/include/linux/tty.h
@@ -239,7 +239,7 @@ struct tty_struct {
        wait_queue_head_t write_wait;
        wait_queue_head_t read_wait;
        struct work_struct hangup_work;
-       void *disc_data;
+       void __rcu *disc_data;
        void *driver_data;
        spinlock_t files_lock;
        struct list_head tty_files;

But in the paragraph "SPARSE CHECKING OF RCU-PROTECTED POINTERS" of
Documentation/RCU/rcu_dereference.rst
we read:
...
Unfortunately, these sorts of bugs can be extremely hard to spot during
review.  This is where the sparse tool comes into play, along with the
"__rcu" marker.  If you mark a pointer declaration, whether in a structure
or as a formal parameter, with "__rcu", which tells sparse to complain if
this pointer is accessed directly.  It will also cause sparse to complain
if a pointer not marked with "__rcu" is accessed using rcu_dereference()
and friends.
...
Use of "__rcu" is opt-in.  If you choose not to use it, then you should
ignore the sparse warnings.
...

So, I think that by adding the '__rcu' annotation we would have new
warnings in all those points
where disc_data is accessed directly (which are many more than those
where rcu_dereference() is used).

If I'm not mistaken, the warning also refers to code that my series
hasn't touched. Also, in the 'BUILD REGRESSION'
report, the slcan warning is found under the 'Unverified Error /
Warning (likely false positive, please contact us if interested)'
section.

So, can it be okay to think about leaving everything as it is, and
then not apply any patches to remove this warning?

Thanks and regards,
Dario

Oh, I didn't check that myself.

So some old code just came into focus :-/

Yes. With this this background leaving the code as-is seems to be 
appropriate too. Thanks for the explanation!

Maybe Marc has another opinion. So let's wait for his feedback ...

This is not a regression, so leave as is for now.

I'm not sure where we stand with all that goings on here with an rc8 and
the concerns raised by Hugh, but I can produce a fix for these issues if
you'd like?
