From d677203a9b38b389184a4e2c43c6cd8f8e5b20d4 Mon Sep 17 00:00:00 2001 From: Richard Yao Date: Sun, 14 Sep 2014 23:39:03 -0400 Subject: Remove blk_queue_discard() autotools check This autotools check was never needed because we can check for the existence of QUEUE_FLAG_DISCARD in the kernel headers.
