Subject: [PATCH v2 6/6] KVM: arm64: rename functions for invariant sys regs
Date: Fri, 26 Apr 2024 12:49:50 +0200 [thread overview]
Message-ID: <20240426104950.7382-7-sebott@redhat.com> (raw)
In-Reply-To: <20240426104950.7382-1-sebott@redhat.com>
Invariant system id registers are populated with host values
at initialization time using their .reset function cb.
These are currently called get_* which is usually used by
the functions implementing the .get_user callback.
Change their function names to reset_* to reflect what they
are used for.
