Hi,

I am reading the lib9p/ramfs.c file and I can't understand this (in threadmain):

+ Qid q;
+ ...
+ q = fs.tree->root->dir.qid;

Because *q* is not longer used.

Why *q* is defined and assigned?

Thanks

Saludos, kix.

Pragmatically, because the Plan 9 C compilers
don't warn about set and not used for struct values.
It's certainly just a dreg.
