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).
The branch is based on your 'for-linus'.
Thanks!
