Subject: [PATCH v8 01/14] KVM: X86: Change parameter for fast_page_fault tracepoint
Date: Tue, 31 Mar 2020 14:59:47 -0400	[thread overview]
Message-ID: <20200331190000.659614-2-peterx@redhat.com> (raw)
In-Reply-To: <20200331190000.659614-1-peterx@redhat.com>

It would be clearer to dump the return value to know easily on whether
did we go through the fast path for handling current page fault.
Remove the old two last parameters because after all the old/new sptes
were dumped in the same line.
