Subject: [PATCH v29 10/32] drm/i915/gvt: Change _PAGE_DIRTY to _PAGE_DIRTY_BITS
Date: Fri, 20 Aug 2021 11:11:39 -0700	[thread overview]
Message-ID: <20210820181201.31490-11-yu-cheng.yu@intel.com> (raw)
In-Reply-To: <20210820181201.31490-1-yu-cheng.yu@intel.com>

After the introduction of _PAGE_COW, a modified page's PTE can have either
_PAGE_DIRTY or _PAGE_COW.  Change _PAGE_DIRTY to _PAGE_DIRTY_BITS.
