Subject: [PATCH RFC 1/6] x86/msr: Rename msr_read() and msr_write()
Date: Mon, 20 Apr 2026 11:16:29 +0200	[thread overview]
Message-ID: <20260420091634.128787-2-jgross@suse.com> (raw)
In-Reply-To: <20260420091634.128787-1-jgross@suse.com>

Rename the existing msr_read() and msr_write() functions to
msr_do_read() and msr_do_write(), as the original names will be used
for new MSR access functions in the future.

Signed-off-by: Juergen Gross <jgross@suse.com>
