From 27eb13e99b515c52ba5a151a1acce6afb8a9b2b6 Mon Sep 17 00:00:00 2001 From: Philipp Reisner Date: Fri, 30 Mar 2012 14:12:15 +0200 Subject: [PATCH] drbd: Fixed processing of disk-barrier, disk-flushes and disk-drain Since drbd_bump_write_ordering() is called in the attaching process while the disk state is D_ATTACHING, it was not considering these three flags during attach. A call to this function was missing form drbd_adm_disk_opts(). Fixed both issues.
