From 2385327725419a76cfbca7258abd95908b8ba9eb Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Tue, 7 Apr 2009 08:59:11 +0200 Subject: block: remove unused REQ_UNPLUG The request inherits the unplug flag from the bio, but it isn't actually used. The bio flag stops at __make_request(), which tells it to unplug after submission. Passing it on to the request doesn't make any sense.
