Stable: The offending commit a82afdf was released with v2.6.32, so
this patch should be applied to all kernels since then but it must
_NOT_ be applied to kernels earlier than that.

If only this patch goes into stable, do we need to change RWA_MASK
in this patch also(I have seen you change it the 2/2)?

-#define RWA_MASK        2
+#define RWA_MASK        16

I think RW_MASK and RWA_MASK should simply go away, they don't server
any use over just masking the correct REQ_* flags.
