Subject: FUSE triggering BUG through blkdev_put()

Please take a look at the following bug.

 https://bugzilla.kernel.org/show_bug.cgi?id=28642

The bug title and description are completely misleading but the
problem seems to have been caused by the recent eviction related
changes.  FUSE ends up blkdev_put'ting while I_CLEAR is still set on
the blkdev's inode triggering BUG_ON() in iput().

Thanks.
