Subject: [GIT PULL] Block fixes for 4.8-rc1

Hi Linus,

Here's the 2nd round of block updates for this merge window. It's a mix
of fixes for changes that went in previously in this round, and fixes in
general. This pull request contains:

- Fixes for loop from Christoph

- A bdi vs gendisk lifetime fix from Dan, worth two cookies.

- A blk-mq timeout fix, when on frozen queues. From Gabriel.

- Writeback fix from Jan, ensuring that __writeback_single_inode() does
   the right thing.

- Fix for bio->bi_rw usage in f2fs from me.

- Error path deadlock fix in blk-mq sysfs registration from me.

- Floppy O_ACCMODE fix from Jiri.

- Fix to the new bio op methods from Mike. One more followup will be
   coming here, ensuring that we don't propagate the block types outside
   of block. That, and a rename of bio->bi_rw is coming right after -rc1
   is cut.

- Various little fixes

Please pull!
