From 8605067fb9b8e34aecf44ec258657c9cc009fc5a Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Thu, 5 Apr 2012 16:04:52 +0100 Subject: [PATCH 1/3] xen-blkfront: module exit handling adjustments The blkdev major must be released upon exit, or else the module can't attach to devices using the same majors upon being loaded again. Also avoid leaking the minor tracking bitmap.
