Hi,
/*
* To allow safe resume of do_memory_op() after preemption, we need
to know
* at what point in the page list to resume. For this purpose I
steal the
* high-order bits of the @cmd parameter, which are otherwise unused
and zero.
*/
#define MEMOP_EXTENT_SHIFT 4 /* cmd[:4] == start_extent */
#define MEMOP_CMD_MASK ((1 << MEMOP_EXTENT_SHIFT) - 1)
Why not using another hypercall argument for this?
Before I''m making any changes.. are there any limitations?
Thanks,
Guy.
