Is this OK?

Or should be

for (i = 0; i < PAGES_PER_PACKET; i++) {
- pkt->pages[i] = alloc_page(GFP_KERNEL);
+ pkt->pages[i] = alloc_page(GFP_KERNEL| __GFP_ZERO);

It definitely should be the latter.

CCing Christoph so he can fix this up.

Correct. Please submit the patch. I see a patch that fixes a pktcdvd.c
issue in Andrews tree so it was likely already fixed without me hearing of
it.
