Subject: [Cocci] Easy search for elements besides binary operators with SmPL

Hello,

I would like to check also the application of elements which are used together
with binary operators like the following.


@find@
expression target;
identifier action;
@@
 target = action(...,
                 ...
*                | __GFP_NOFAIL
                 | ...,
                 ...);

?
minus: parse error: 
  File "/home/elfring/Projekte/Coccinelle/janitor/show_use_of_nofail1.cocci", line 6, column 17, charpos = 87
  around = '...',
  whole content =                  ...


How should I improve my search pattern?


A metavariable can already be used for the search of a function parameter at an
undetermined position within a bigger list. Can similar functionality work also
for binary operators?

Markus
