From 768a418db102bb6aa6064e6090892b5c21ff1f9e Mon Sep 17 00:00:00 2001 From: NeilBrown <neilb@suse.de> Date: Mon, 26 Jul 2010 11:49:55 +1000 Subject: [PATCH] md: add support for raising dm events. dm uses scheduled work to raise events to user-space. So allow md device to have work_structs and schedule them on an error.
