Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/46227 Follow up from https://github.com/pytorch/pytorch/issues/45419, in this PR I've removed as many PyCFunction casts as I could from the codebase. The only ones I didn't remove were the ones with `METH_VARARGS | METH_KEYWORDS` which have 3 parameters instead of 2 and had to be casted. Example: ` {"copy_", (PyCFunction)(void(*)(void))THPStorage_(copy_), METH_VARARGS | METH_KEYWORDS, nullptr},` ghstack-source-id: 114632704 Test Plan: waitforbuildbot Reviewed By: albanD Differential Revision: D24269435 fbshipit-source-id: 025cfd43a9a2a3e59f6b2951c1a78749193d77cf
