From 004a4b38a7a0522c0edfd29c01855f92bec516a1 Mon Sep 17 00:00:00 2001 From: Oleg Drokin Date: Thu, 1 Oct 2015 00:12:19 -0400 Subject: [PATCH] staging/lustre/ldlm: Remove ldlm_init/destroy_export() These functions are used on the server-only, so get rid of them. Also get rid of ldlm export hash operations and the struct.
