#1328383 — [GIT PULL] another floppy fix

Message-ID<qZjdg-5hi-7@gated-at.bofh.it>
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!
