From 31e0cf8f6a1488b6ca69dcdceeaed107ecfd6463 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Tue, 4 May 2010 16:39:35 -0700 Subject: [PATCH] ceph: name bdi ceph-%d instead of major:minor The bdi_setup_and_register() helper doesn't help us since we bdi_init() in create_client() and bdi_register() only when sget() succeeds.
