[Xen-devel] [PATCH] move IO_ASSIST_WRITE tracing flag define

[Andre Przywara <andre.przywara@xxxxxxx>]

Hi,

hvm/emulate.c sets the direction of an IO_ASSIST trace operation in an 
unused bit. This bitmask was defined in the .c file, not in the public 
header. Beside moving this define this patch adds the appropriate string 
in the formats file.
Signed-off-by: Andre Przywara <andre.przywara@xxxxxxx>

Regards,
Andre.
