From 7a5febe9ffeecd1e78c5b505260ccc1ef18021b4 Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 16 May 2005 21:53:16 -0700 Subject: [PATCH] [PATCH] md: set the unplug_fn and issue_flush_fn for md devices *after* committed to creation We we set the too early, they may still be in place and possibly get called even though the array didn't get set up properly.
