[PATCH 073/124] staging: lustre: llite: remove ll_objects_destroy()

From: James Simmons
Date: Sun Sep 18 2016 - 16:56:17 EST


From: John L. Hammond <john.hammond@xxxxxxxxx>

Remove ll_objects_destroy(). This function is not needed for
interoperability with servers of version 2.4 or higher.

Remove the then unused function lov_destroy() and its supporting
functions. Remove the lsm_destroy method of struct lsm_operations.

Remove the unused struct lov_stripe_md, MD export, and capa parameters
from obd_destroy() and its implementations.
