Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: "Here's the second 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" * 'for-linus' of git://git.kernel.dk/linux-block: mm/block: convert rw_page users to bio op use loop: make do_req_filebacked more robust loop: don't try to use AIO for discards blk-mq: fix deadlock in blk_mq_register_disk() error path Include: blkdev: Removed duplicate 'struct request;' declaration. Fixup direct bi_rw modifiers block: fix bdi vs gendisk lifetime mismatch blk-mq: Allow timeouts to run while queue is freezing nbd: fix race in ioctl block: fix use-after-free in seq file f2fs: drop bio->bi_rw manual assignment block: add missing group association in bio-cloning functions blkcg: kill unused field nr_undestroyed_grps writeback: Write dirty times for WB_SYNC_ALL writeback floppy: fix open(O_ACCMODE) for ioctl-only open
