Re: assert macro to check null

Actually WARN_ON macro has been defined slightly differently for each Acrhitecture in kernel. Can you specifically point out the definition of macro you have suggested and where it is defined in kernel. Regards, Saket Sinha On Sat, Aug 10, 2013 at 11:05 AM, <Valdis.Kletnieks@vt.edu> wrote:

get_cred(new); where null is struct cred *new.

I think this new might be NULL.

Now I plan to add an assert in our macro that deals with creds, like for asserting passed object isn't NULL.

Any suggestions as to how I can do that?

WARN_ON(!new);

is probably your best bet.
