Remove __GFP_ZERO from mempool_alloc() in drbd_req_new() and properly
initialize it to 0.
You should add it to mempool instead, avoid having this issue show up
for other folks as well. It'd be trivial to do. Normal ->alloc() should
honor __GFP_ZERO, just do the same manually for removing an item from
the internal pool.
