I find this rejection surprising.


> You don't need so many type metavariables.

I got an other software development opinion for this aspect.

Yesterday we started to clarify consequences from the isomorphism specification
“drop_cast” (for SmPL code).
https://github.com/coccinelle/coccinelle/blob/32d3b89ad909316464344a5f61a8092d8d702321/standard.iso#L52

Information like the following influenced my design decision to add three
metavariables here.

elfring@Sonne:~/Projekte/Linux/next-patched> spatch --parse-cocci scripts/coccinelle/free/put_device.cocci
…
warning: iso drop_cast does not match the code below on line -1
T (T )id

pure metavariable T is matched against the following nonpure code:
T
…


> Type metavariables in the same ... can be the same.

I would find it also occasionally nice when multiple SmPL ellipses
can refer to identical type casts.

* The under-documented “type purity” hinders this at the moment.

* But I got the impression that it can be safer to distinguish these
  code variants better.

Regards,
Markus
