From 23fe8f8b1101ec77befc995ab15fad82d9d91d16 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Tue, 24 Mar 2015 16:22:32 -0700 Subject: block, drbd: fix drbd_req_new() initialization mempool_alloc() does not support __GFP_ZERO since elements may come from memory that has already been released by mempool_free(). Remove __GFP_ZERO from mempool_alloc() in drbd_req_new() and properly initialize it to 0.
