Subject: Proposal: Eliminate GFP_DMA
Date: Fri, 28 Feb 2003 06:46:31 +0000 [thread overview]
Message-ID: <20030228064631.G23865@parcelfarce.linux.theplanet.co.uk> (raw)
I'm thinking about doing something along these lines:
--- linux-2.5.63/include/linux/gfp.h 2003-02-24 13:05:13.000000000 -0600
+++ linux-2.5.63-gfpdma/include/linux/gfp.h 2003-02-27 17:24:39.000000000 -0600
@@ -26,11 +26,8 @@
-/* Flag - indicates that the buffer will be suitable for DMA. Ignored on some
- platforms, used as appropriate on others */
-
-#define GFP_DMA __GFP_DMA
-
+#define GFP_ATOMIC_DMA (GFP_ATOMIC | __GFP_DMA)
+#define GFP_KERNEL_DMA (GFP_KERNEL | __GFP_DMA)
combined with changing some users to use __GFP_DMA if they really do mean
the bitmask. Comments?
