From f15ba52bfabc3bc130053bd73d414d859162de91 Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Wed, 8 Feb 2023 15:01:04 +0100 Subject: KVM: Standardize on "int" return types instead of "long" in kvm_main.c KVM functions use "long" return values for functions that are wired up to "struct file_operations", but otherwise use "int" return values for functions that can return 0/-errno in order to avoid unintentional divergences between 32-bit and 64-bit kernels. Some code still uses "long" in unnecessary spots, though, which can cause a little bit of confusion and unnecessary size casts. Let's change these spots to use "int" types, too.
