From d56b9b28a4a5d9e61dd99154b986e760373e2392 Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Mon, 23 Feb 2015 19:10:15 -0500 Subject: dm: remove request-based DM queue's lld_busy_fn hook DM multipath is the only caller of blk_lld_busy() -- which calls a queue's lld_busy_fn hook. Request-based DM doesn't support stacking multipath devices so there is no reason to register the lld_busy_fn hook on a multipath device's queue using blk_queue_lld_busy(). As such, remove functions dm_lld_busy and dm_table_any_busy_target.
