[lustre-devel] [PATCH 27/27] lustre: obd: remove unused obd_evict_inprogress

[James Simmons]

From: Timothy Day <timday at amazon.com>

Remove the atomic_t struct field obd_evict_inprogress
from 'struct obd_device'. This field was only ever
incremented in a unused function that was removed in
a previous patch. Hence, remove it altogther. This
patch also removes the associated wait queue.
