Re: omapfb/dss: Delete an error message for a failed memory allocation in three functions

Many people do not know that a generic kmalloc does a
dump_stack() on OOM.

This is another interesting information, isn't it?

It is expected that the function “devm_kzalloc” has got a similar property.

You don't have to expect this.  Go look at the definition of devm_kzalloc
and see whether it has the property or not.

I find that the corresponding documentation of these programming interfaces
is incomplete for a desired format which could be different than C source code.

Can the Coccinelle software help more to determine desired function properties?

For which hardware and software combinations would you like to see
facts there?

This is not for Joe to decide,

This view is fine in principle.

it's for the person who receives the patch to decide.

I am curious on further comments from these contributors.

You could start with the ones for which the code actually compiles,
using the standard make file and no special options, and a
recent version of gcc.

The variation space could become too big to handle for me (alone).
How will this aspect evolve further?
