I get this error:

elist.h:184:10: error: expected expression before ‘)’ token
  ((type *)((char *)(ptr)-(intptr_t)(&((type *)0)->member)))
          ^

Full code snippet:
#define list_entry(ptr, type, member) \
	((type *)((char *)(ptr)-(intptr_t)(&((type *)0)->member)))

This is not the full source which is having issues.
This is only the header file where the #define is located.
I suspect you are using list_entry incorrectly.  Though the error message could be better.

Please provide a minimal self-contained testcase showing the problem.
Comment 3 Marek Polacek 2013-10-21 20:50:04 UTC 
Testcase not coming.
