Subject: [Cocci] Match variable declaration with init expression
Date: Fri, 31 Jul 2020 15:40:21 +0300
Message-ID: <ba2b2337-2c58-4029-938b-05184a23a758@linux.com> (raw)

Hi,

This pattern:
- E = kzalloc(size, flags | __GFP_NOWARN);
- if (\(!E\|E == null\))@p
-   E = vzalloc(size);
+ E = kvzalloc(size, flags);

matches this code:
void *p;
p = kzalloc(size, gfp | __GFP_NOWARN);

if (!p)
	p = vzalloc(size);

But not this:
void *p = kzalloc(size, gfp | __GFP_NOWARN);

if (!p)
	p = vzalloc(size);

What can I do to match them both?

Thanks,
Denis
