Subject: [PATCH] KVM: x86/mmu: Add '__func__' in rmap_printk()
Date: Wed, 27 Jan 2021 10:08:45 +0800 [thread overview]
Message-ID: <1611713325-3591-1-git-send-email-stephenzhangzsd@gmail.com> (raw)
Given the common pattern:
rmap_printk("%s:"..., __func__,...)
we could improve this by adding '__func__' in rmap_printk().
