Subject: [PATCH v5 09/10] KVM: arm64: rename functions for invariant sys regs
Date: Wed, 19 Jun 2024 17:40:35 +0000 [thread overview]
Message-ID: <20240619174036.483943-10-oliver.upton@linux.dev> (raw)
In-Reply-To: <20240619174036.483943-1-oliver.upton@linux.dev>
From: Sebastian Ott <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.
