From 170b2c350cfcb6f74074e44dd9f916787546db0d Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Thu, 16 Jun 2022 16:36:17 +0200 Subject: usercopy: use unsigned long instead of uintptr_t A recent commit factored out a series of annoying (unsigned long) casts into a single variable declaration, but made the pointer type a `uintptr_t` rather than the usual `unsigned long`. This patch changes it to be the integer type more typically used by the kernel to represent addresses.
