From e1708ad71433b01ed38fa5468bc0e8e95fc267fb Mon Sep 17 00:00:00 2001 From: Oleg Drokin Date: Wed, 16 Sep 2015 12:27:04 -0400 Subject: [PATCH] staging/lustre: Remove unused OBD_ALLOC* and OBD_FREE macros This removes now unused OBD_ALLOC, OBD_ALLOC_GFP, OBD_ALLOC_PTR, OBD_ALLOC_LARGE and supporting infrastructure. Also OBD_FREE, OBD_FREE_PTR, OBD_FREE_LARGE and supporting infrastructure.
