[lustre-devel] [PATCH 36/45] lnet: use kmem_cache_zalloc as appropriate.

[James Simmons]

From: Mr NeilBrown <neilb at suse.de>

Rather than passing __GFP_ZERO to kmem_cache_alloc(), or calling
memset(0) after the allocation, use kmem_cache_zalloc().

kmem_cache_zalloc() has been part of Linux since 2.6.17.

WC-bug-id: https://jira.whamcloud.com/browse/LU-6142
