From f00ccdede3c84df2287e59b546fd92d58b7e07af Mon Sep 17 00:00:00 2001 From: Yosry Ahmed Date: Tue, 13 Jan 2026 17:28:07 +0000 Subject: [PATCH] KVM: nSVM: Drop redundant/wrong comment in nested_vmcb02_prepare_save() The comment above DR6 and DR7 initializations is redundant, because the entire function follows the same pattern of only initializing the fields in vmcb02 if the vmcb12 changed or the fields are dirty, which handles the first execution case. Also, the comment refers to new_vmcb12 as new_vmcs12. Just drop the comment. No functional change intended.
