Jens,

please pull from

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/linux-block.git for-4.5/for-jens

to receive another floppy fix for bug found by syzkaller tool (and
reported by Dmitry Vyukov); this time O_NONBLOCK handling is (and has
always been) broken for /dev/fdX, potentially leading to all kinds of
havoc (syzkaller is able to livelock the system in mm because of this
bug).

Pulled, thanks.
