Hi,
I'm trying to write the check to detect the absence of commit

in kernel. The pattern can be:
@err exists@
identifier namlen, dchild, dparent, exp;
position p;
statement S;
@@
compose_entry_fh(..., int namlen, ...)
{
...
if (namlen == 2) {
* dchild =@p dget_parent(dparent);
... when != dparent == exp->ex_path.dentry
add when forall here. There does exist a path that does not contain the
dparent == exp->ex_path.dentry test. That is the path that takesthe first
goto out.
This solved the problem, thanks!
