From 6e51f085f64a79c7647e88a8a019b7bd84f42255 Mon Sep 17 00:00:00 2001 From: Christof Schmitt Date: Fri, 30 Apr 2010 18:09:37 +0200 Subject: [SCSI] zfcp: Zero memory for gpn_ft and adisc requests With debug kernels, the memory allocated with kmem_cache_alloc might be initialized with the poison values 6b and a5. Use kmem_cache_zalloc instead of kmem_cache_alloc to get zeroed memory and not send invalid requests.
