From 3ea9b809650b4eda5d4ae18ed7bb080e499af154 Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Fri, 27 May 2022 15:13:03 -0700 Subject: KVM: selftests: Add kvm_has_cap() to provide syntactic sugar Add kvm_has_cap() to wrap kvm_check_cap() and return a bool for the use cases where the caller only wants check if a capability is supported, i.e. doesn't care about the value beyond whether or not it's non-zero. The "check" terminology is somewhat ambiguous as the non-boolean return suggests that '0' might mean "success", i.e. suggests that the ioctl uses the 0/-errno pattern. Provide a wrapper instead of trying to find a new name for the raw helper; the "check" terminology is derived from the name of the ioctl, so using e.g. "get" isn't a clear win.
