Pull SCSI fixes from James Bottomley: "This is our remaining set of three fixes for 4.0: two oops fixes(one for cable pulls triggering oopses and the other be2iscsi specific) and one warn on in sysfs on multipath devices using enclosures" * tag 'scsi-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi: Defer processing of REQ_PREEMPT requests for blocked devices be2iscsi: Fix kernel panic when device initialization fails enclosure: fix WARN_ON removing an adapter in multi-path devices
