[Xen-devel] question about xl migrate

["Zhang, Chunyu" <zhangcy@xxxxxxxxxxxxxx>]

hi all

i have two question about xl migrate

write_batch
120     for ( i = 0; i < nr_pfns; ++i )
121     {
122         types[i] = mfns[i] = ctx->save.ops.pfn_to_gfn(ctx,
123                                                       
ctx->save.batch_pfns[i]);
124 
125         /* Likely a ballooned page. */
126         if ( mfns[i] == INVALID_MFN )
127         {
128             set_bit(ctx->save.batch_pfns[i], ctx->save.deferred_pages);
129             ++ctx->save.nr_deferred_pages;
130         }
131     }

1.  line 122
in hvm mode, is not mfns, but gfns.
right?

2. line 125
in hvm mode,would not be a balloon page.
gfn would not be INVALID_MFN.
mfn would be INVALID_MFN.
right?

if what i think is right, maybe we can change those code ?
