[Cocci] minus: parse error:

[Greg McGary]

 Any clues about this?

Consider this:

@ ioctl_ref @
identifier fops_id;
identifier ioctl_id;
@@
struct file_operations fops_id  = {
    ...
(
    .unlocked_ioctl
|
    .compat_ioctl
)
    = ioctl_id,
    ...
};

spatch barfs like so:

init_defs_builtins: /usr/share/coccinelle/standard.h
Fatal error: exception Failure("minus: parse error:
 = File "/home/gnu/linux-2.6/ioctl-5.cocci", line 10, column 1,  charpos = 112
    around = '.', whole content =       .unlocked_ioctl
")

OK, so it doesn't understand named-member struct initializers.  Maybe I could drop the "." it doesn't like:

@ ioctl_ref @
identifier fops_id;
identifier ioctl_id;
@@
struct file_operations fops_id  = {
    ...
(
    unlocked_ioctl
|
    compat_ioctl
)
    ioctl_id,
    ...
};

no such luck:

init_defs_builtins: /usr/share/coccinelle/standard.h
Fatal error: exception Failure("minus: parse error:
 = File "/home/gnu/linux-2.6/ioctl-5.cocci", line 14, column 1,  charpos = 146
    around = 'ioctl_id', whole content =        ioctl_id,
")
